3.3 Function Details (and Parameter Detail Settings)
3.3.1 Tilt Angle/Beam Angle
You need to change the measurement mode according to your measuring purpose.
For the reflection angle measurement, select "Tilt Angle".
For the external light angle measurement, select "Beam Angle".

For the reflectance angle measurement
It starts reflection angle measurement.

Set "Angle Type" in option
settings to [Beam Angle].

43

3.3.2 Divergence
Divergence indicates how much the light beam expands at an angle as it propagates.
A light beam with small divergence means that there is little expansion during propagation overlong distance, while a beam with a large divergence expands rapidly over short distance.
The Products display divergence in a half-angle with mrad (milli radian). It has two modes ofmeasurement.
To measure D4σ beam diameter (elliptical beam) of divergence along with X-axis and Yaxis directions.
Measures beam divergence with "D4Sigma X" and "D4Sigma Y"

Set "Orientation Enabled" inthe option settings to"Disabled".

To measure a D4σ beam diameter (elliptical beam) of divergence along with M (major: longaxis) and m (minor: short axis).
Measures beam divergence with
“D4Sigma M” and “D4Sigma m”

Set "Orientation Enabled" inthe option settings to"Enabled".

44

3.3.3 Beam Centroid
The center position of a light spot can be selected by the type either beam area (area centroid)and beam intensity (luminance centroid) in the "Beam Centroid" in the option setting. It is
recommended to select the type of "Beam Centroid" according to an object to be measured.
Area Centroid (Area)
For the area centroid of a light beam, its centroid position is calculated from an irradiated area
higher luminance than the denoising threshold value and results as an angle. Therefore, by
raising the threshold value, the effects of the edges of the peak profile can be minimized.
It is recommended to select this type of measurement for objects such mirror with uniform
surface and reflects a light beam without blur or smudge*.
※ Optically, blur or smudge is defined as, for instance, luminous point with elongating edge profile
in normal distribution, half-width deviating largely from normal distribution, or objects withirregular profiles which are not smooth.

Intensity Centroid
For luminance [Intensity] centroid, the centroid position of a light beam is calculated from thebeam intensity with higher luminance than the denoising threshold value and results as anangle.
By lowering the threshold value, the Intensity Centroid can include the luminous point peripheralarea causing blur or smudge.
It is recommended to select this type of measurement mode for objects such mirror withuniform surface which reflects a light beam without blur or smudge*.
It is recommended to select this type of measurement mode for objects such as resin with nonuniform surfaces which reflects a light beam with blur or smudge.

3.3.4 Beam Ellipticity
Beam Ellipticity determines how far the light beam shape is deformed from circular toelliptical.
Beam ellipticity formula:
Beam Ellipticity = D4 σ m (minor) beam diameter / D4 σ M (major) beam diameter
The following describes its use.
Beam Ellipticity Usage
1. The beam spots of "Sub 1" and "Sub 2" shown in the rightare incident lights on the sensor head, and the angles ofeach can be measured.

Sub1

Sub2

We move the two beam spots close to each other so that
the Sub1 and Sub2 are nearly parallel.

2. As the two beam spots move closer together, the sensor
begins to perceive them as a single elliptical beam.
Therefore, it is no longer possible to measure their

Sub2
Sub1

individual angles or their parallelism.

47

3. On this state as mentioned above, thebeam ellipticity function should be applied.
Sub2
Sub1

The beam is displayed in ellipticity.

3. Move the two beams even closer together. Closer the ellipticity to “1.000” and the two targets
are nearer to parallel.

Sub2
Sub1

For ellipticity measurement

Set "Orientation Enabled" inoption settings to "Enabled".

48

3.3.5Judgement

The judgement function is available in an intuitively understandable expression of whether themeasurement value is within the target range or not.
Here, as examples, we have the procedures for Angle (D) and Peak.

For Angle (D)① Adjusting the angle and aim to set the "Angle(D)" of the measurement result to lessthan 0.5000.
Enabling the “Angle(D)” in the “Judgement Settings” in the Option setting and enterthe value to be “0.5000 deg”.

49

2. As a result of adjusting the angle, the result of Angle D on the measurement screen is notless than 0 .5000 deg, so the judgment result is “NG”at the“Tilt Angle(D)”of the“Judgement”.

3. As a result of adjusting the angle one more time, the result of Angle D on the measurement screen
is less than 0.5000 deg, so the judgment result of "Tilt Angle(D)" in "Judgement" is displayed as
OK.

50

For Peak
1. Adjusting the light intensity and set the “Peak” of the measurement result to be less than
3500.
Set “Peak” to “Enable” in the “Judgement Settings” option and set it to “3500.0.”51

2. Because the result of Peak light intensity adjustment on the measurement screen is not lessthan 3500.0, the judgement result is “NG,” and the peak bar is in red.

3. When the result of repeated Peak light intensity adjustment on the measurement screen is lessthan 3500.0, the judgement result is “OK” and the peak bar is in green.

52

3.3.6 Adaptive Cal
The "Adaptive Cal" is a function that improves beam calculation accuracy by removing noisefrom the entire sensor. This function is an automatic denoising function that calculates thebaseline correction value from the entire sensor and offsets it from the pixel data of eachpixel.
It is recommended to run this function when starting up the application and every time theexposure time in the camera settings is changed.
1. Set the beam not to enter the product.
2. Click the “Adaptive Cal” button.

53

3. When adaptive calibration is executed, the button color changes.
4. When "Adaptive Calibration succeeded" is displayed in the System Log, the process iscomplete.
5. Thereafter, set the beam incoming to the product and begin measurement.

Note:
If the beam is incoming to the product or the ambient light is causing serious noise, adaptive
calibration will not succeed. Execute in an environment where light does not enter the sensor
camera.

54

3.3.7 Aperture
The “Auto Aperture” and “ROI” settings are available to make sure that the effects of noisesuch as ambient light are not included in the beam divergence measurement results.
By using these two functions, measurement excluding ambient light can be done.

Orange Line:
Aperture by the Auto Aperture setting

Light blue dotted line:
Aperture by the ROI setting

Aperture Explains.
This function is suitable for measuring dynamic beams in which theAuto Aperture

position, size, shape, or intensity of the beam may vary over time.
It automatically adjusts aperture.
This function is suitable for measuring beams in which position, size,

ROI

shape, and intensity rarely vary with time.
The aperture must be adjusted manually.

Info
Auto Aperture and ROI together can enhance only the important parts of the beam intensity,
shape, and position, and by minimizing noise and interference it improves the accuracy ofmeasurement.
It is recommended that both be used simultaneously in situations where the beam position
does not change.

55

Setting Methods
For Setting Auto Aperture

Set “Auto Aperture” in option settings to[Enabled]

For Setting ROI
Enable "ROI" in the option settings and set
the X, position, width, Height (size) to

Settings, and set the X,Y (location), Width,and Height (size) of the "ROI".

56

3.3.8 Origin Offset
The Origin Offset function offsets the sensor camera center position from the default position to
any position as desired.
By using the offset function, an arbitrary position can be aligned as the reference position.
There are two offset methods.

Setting Methods
For Setting from the Option Screen
Ex.: Set at X = 0.5deg, Y = 0.5deg

Set “Origin Offset” inoption settings to thedesired values.

2. A pop-up window will be displayed.

3. Drag and drop the display to be enlarged, and a zoomed area will appear.

58

4. Right-click to quit the zooming display.

5. To close the pop-up window, click the [X] button.

59

3.3.10 Multi Spot
The Products support multi-spot measurement of up to 100 spots simultaneously.
The use of the Multi Spot setting enables the measurement results screen display order andnumber to be set.
Detection conditions can also be set to filter measurement targets.

Ex. Explaining the screen for detection of multiple beams (4 spots)

4 incidents
By changing "Number", the corresponding Number(No.) in the list below can be displayed in
the Title Angle at the top.
