Line scan camera: An allPIXA SWIR camera, which scans the image line by line andcommunicates with the PC (5).

1

The optical system: Optical lenses with tubes and mounts with an adjusted focusing

2

Illumination: The illumination system lights up the information carrier / scan area on
the passing object. The Chromasens Corona II SWIR illumination system is an ideal
supplementary option for the allPIXA SWIR camera.

3

Illumination controller: Controls and monitors the illumination unit. The Chromasens
Corona II illumination (3) has integrated temperature sensors which can be read out
with the XLC4 controller. By use of the XLC4 controller, the illumination unit can bemonitored and kept stable.

4

Network cable and suitable network adapter: The image data are sent to a PC
using a standard 1000BASE-T network connection. Use a Cat-5e, Cat-6, or better
S/STP Gigabit Ethernet cable and a suitable Gigabit Ethernet network adapter in thePC.

5

PC: The PC system performs subsequent processing of the image data and canoptionally control the illumination system (3 + 4).

6

Speed control: The line rate of the camera can be controlled and synchronized withthe transport speed of the object or conveyor belt by means of an optional rotary
encoder or external line trigger signal. Synchronization of the camera with strobed
illumination is also possible this way.

7

Conveyor unit: The conveyor unit moves the scanned object past the allPIXA SWIR
camera.

8Power supply: Both, the allPIXA SWIR camera and the illumination system, require a
suitable power supply.

allPIXA SWIR – basic functionality

4.1

Basic design of the allPIXA SWIR camera
During operation, an object is scanned line by line by the InGaAs sensor.
The FPGA also includes a softcore microcontroller (or microprocessor) with its peripherals like
RAM and flash memory. The software running in the microcontroller configures and supports
the FPGA logic to process and transfer image data and to communicate with the hostapplication.
The allPIXA SWIR camera can be used and configured with any GigE Vision 2.0 compliant
Software or SDK. We recommend using the Chromasens GenICam Control Tool (GCT) and theChromasens SDK which is available for Linux and Windows. The Windows SDK is an optional
component of the GCT installer, the Linux SDK is available on request.
External trigger signals from sources like incremental encoders, light barriers, or light and trigger
controllers can be input by the GPIOs (general purpose inputs/outputs) of the Digital I/O
connector of the GigE models or by the CC of the camera.

Using an encoder or external triggers
Acquisition Start, Frame Start and Line Start can optionally be triggered by (synchronizedwith) external trigger sources like rotary encoders or light barriers.

PMA_CHR_CD40199_R01_allPIXA_SWIR_GigE_User_Manual.docx

23Line Start (an hence the line frequency of the camera) can be controlled either directly by atrigger signal matching the intended camera line frequency or by the signal of an incremental
encoder, e.g. mounted on a conveyor belt.
When the frequency (resolution) of the incremental encoder does not match the frequency
required for the line trigger of the camera (which depends on the optical resolution of thecamera), the resulting image will be distorted. The distortion can be corrected by means of theEncoder Divider Float parameter of the camera's Encoder Control feature.
Refer to section 5.3.1 when using an incremental encoder as line trigger source and to section
5.3.2 when providing the external line trigger signal directly.
If you want to control frame start e.g., by means of a light barrier, please refer to section 5.3.3.

5.3.1 Using an encoder as line trigger source
Application example: scanning objects on a conveyor belt moving with variable speed. Adapt
camera line rate to transport speed of the object by means of an incremental encoder signal to
get undistorted images. Refer to section 5.6 and 5.1.3 on how to connect the incremental
encoder to the digital I/O connector of the camera.
To configure the camera for rotary encoder usage:
1. select Line Start in the Trigger Selector of the Acquisition Control feature group.
2. Set Trigger Mode to On.
3. Select Encoder as Trigger Source:

4. In the Encoder Control feature group, open Encoder Selector.
5. Select the I/O lines the encoder is connected to as Encoder Source A and Encoder
Source B, e.g., when encoder output A is connected to camera input Line 1 andencoder output B is connected to camera input Line 1, encoder settings should look
like this:

6. Encoder Mode has two possible settings:•

Four Phase: The counter increments or decrements 1 for every full quadrature
cycle with jitter filtering.

•High Resolution: The counter increments or decrements every quadrature phasefor high resolution counting, but without jitter filtering.

7. Encoder Output Mode has two possible settings:•

Motion: Output pulses are generated in both directions.

PMA_CHR_CD40199_R01_allPIXA_SWIR_GigE_User_Manual.docx

24•

Direction Up: Output pulses are generated only in the positive direction while
motion in negative direction will be ignored.

If only a single encoder line is connected, make sure that Encoder Output Mode has
the value Motion. In this case, the rotating direction of the encoder cannot be
detected.
8. Encoder Divider Float specifies the number of encoder steps needed to generate an
encoder output pulse (to be used as line trigger).

Adjust the value when required according to transport speed, optical resolution of thecamera and the pulses per revolution of the encoder.
The correct value can be calculated using the formulas in the calculation example
below.

Adjusting camera and illumination◼

Put camera and illumination in operation as described in section 7.1 and 7.2 above.
Refer to the user manual of the illumination system for details on setting up and operating theillumination.

◼

Prepare a suitable white reference target.
NOTE

The white reference target must cover the full scanning width. It must be placed in
the object plane of the scanning system. Even very small damages or stains on
the white reference can seriously affect the quality of the PRNU calibration. Whenpossible, use professional, diffuse reflecting white reference targets (typicallymade of sintered PTFE or ceramics). The white reference should move during the
PRNU calibration process. The movement results in averaging, which helps tomitigate the negative effect of dust and scratches on the white reference.

◼

Keep ready appropriate sharpness test patterns to measure and optimize focus andmagnification across the scan width. Stripe patterns with known spatial resolution are suitable
for this purpose.

◼

Further useful tools:•

An infrared detector card can be helpful to make the beam of the SWIR illumination
visible while adjusting the illumination.

•

Special adjustment tools or rulers customized to your scanning system can be very
helpful when setting up and aligning camera and illumination.

To adjust the camera setting to your operating conditions, follow the steps below.

◼

Prepare the scanning system for calibration:•

Set the camera to continuous, free-running mode by loading the Default user set.

•In the Image Calibration Control feature group, disable Flatfield Correction for both
PRNU and DSNU:•

Click Start grabbing•

Place the white reference target into the object plane of the scanning system.

1in the GCT toolbar to get a live image from the camera.

Align system components:

2•

Illumination alignment:
Switch on the illumination and align it optimally with the scanning area. The line captured by
the camera should be illuminated as homogeneously and brightly as possible.

•

Camera alignment:
Align the camera exactly perpendicular to the transport direction and to the center of the
optimally illuminated area.

•

Focusing and f-stop:
Set an appropriate f-stop and focus the camera using sharpness test patterns in the object
plane. Compare sharpness and magnification in the center of the image and at the edges toachieve an optimal result.

•

If the image is overexposed or too dark to accurately judge sharpness and alignment,
continue with step 3 and repeat step 2 afterwards.

PMA_CHR_CD40199_R01_allPIXA_SWIR_GigE_User_Manual.docx

35

Adjust integration time, sensor gain and illuminance (LED current):•

In the Acquisition Control feature group, adjust Exposure Time to get a normally exposed
image.

.
“Normally exposed” means that the gray values of the brightest parts of the white reference
image are approx. 60-80% of the maximum value for the selected bit depth.
For the respective maximum value see Pixel Dynamic Range Max in the Component
Selector of the Image Format Control feature group:3•

When the Resulting Line Rate drops below your speed requirements (defined by camera
resolution and transport speed), increase illumination intensity (LED current) or Sensor
Gain in the Gain Selector of the Analog Control feature group:

Please note: For optimal image quality keep both sensor gain and digital gain as low as
possible. The higher the gain, the worse the signal-to-noise ratio and overall image quality.

Save settings and reference images:
4

Optionally, you can grab and safe an image of the white reference, a dark image (captured
with covered lens) and the camera settings you came up with for future reference. For
information on grabbing and saving images and user settings refer to the GCT user manual.

7.4

Creating flat field correction tables
Flat field correction (FFC) is used to eliminate vertical stripes and inhomogeneities in theimage caused by fixed pattern noise of the image sensor, vignetting of the lens and nonuniformity of illumination.
FFC can be performed in-camera using separate correction datasets for dark signal nonuniformity (DSNU) and photo response non-uniformity (PRNU).
The camera is delivered with generic factory FFC datasets (factory calibrated DSNU and PRNU
correction tables).
Once the operating conditions are set, user DSNU and PRNU correction tables should becreated and used instead of the Factory settings in order to achieve optimal scan results.
When the operating conditions change (e.g. when the lens is changed, the camera is
repositioned, the aperture is adjusted, or illumination, sensor gain or exposure time is changed)
the user DSNU and PRNU datasets should be updated to match the new operating conditions.
User DSNU and PRNU datasets can be created or updated using in-camera calibration wizards.
Make sure that image sensor, lens, illumination, and white reference target are free of dust anddirt before creating or updating your user DSNU and PRNU datasets.
To avoid damage to the camera, please contact Chromasens support for
instructions on image sensor cleaning.

◼

When you execute the Calculate User Coefficients command, the DSNU calibration wizard
will automatically capture a dark image, calculate a new DSNU correction table from the dark
image and overwrite the existing User DSNU Dataset with the newly created table.
Therefore, make sure to cover front lens and/or turn the illumination off before executing thecommand.

◼

In a similar way, the PRNU calibration wizard will capture and use an image of the (moving)white reference to calculate and overwrite the User PRNU Dataset.

◼

Both images must be captured under typical operating conditions. Refer to section 7.3 forrequired camera adjustments and further details on the white reference target.
DSNU and PRNU calibration can be performed either in free-run mode or with external line
and/or frame triggers. Sometimes it is easier to perform the calibration in free-run mode, even if
the camera is operated in normal mode with external line and or frame triggers. You might wantto prepare a special user set for this purpose and download it to the computer for later use.
Make sure to set up the camera accordingly or upload the user set to the camera that may havebeen prepared before for this purpose. Refer to section 7.3 for camera adjustment in free-runmode and to section 5.3 for setting up external triggers or encoder signals.
In any case, it is important to perform FFC calibration under typical operation conditions, thismeans:◼

Camera sensor and illumination should already have reached normal operating temperature
before you start the calibration.

◼

Sensor gain, exposure time, and when possible, also line rate should correspond to theparameters in normal operation.

◼

The white reference target should be placed exactly in object plane and should move during
the PRNU calibration.
If a PRNU calibration with moving object is not possible, the camera can be slightly defocusedfor the PRNU calibration, for example. However, optimal results can only be achieved under theabove-mentioned operating conditions.

◼

To create or update the DSNU and PRNU correction tables, follow the steps below.

PMA_CHR_CD40199_R01_allPIXA_SWIR_GigE_User_Manual.docx

37

Safe or restore camera settings for FFC calibration:
Currently only one user set (User Set 1) can be stored in the camera and saving it will
overwrite the previous setting, but you can download user settings from the camera as files
to your computer and restore them for later use. The same applies to user DSNU and
PRNU correction tables. Please refer to the GCT manual for details about uploading anddownloading files from/to the camera.

1•

When you use different settings for calibration and normal operation, it is recommended tosave the settings used for FFC calibration to User Set 1 and download this user setting also
to a file on your computer and restore it for later re-calibrations.

•

To save the current camera settings to User Set 1, select User Set 1 in the User Set
Selector of the User Set Control feature group, then execute the User Set Savecommand.

Generate User DSNU correction:•

Open the Image Calibration Control feature group and select DSNU in the Flatfield
Correction selector. Cover the lens, then execute Calculate User Coefficients to
update/overwrite the user DSNU correction of the camera.
