X-ray Time Delay Integration (TDI) CMOS camera

Harrier CMOS TDI
allows faster scan rates or reduction in X-Raypower.
Normally, reducing pixel size in half will reduce
the signal to each pixel by 4 times but TDI
technology allows the resolution to be
doubled while retaining very similar sensitivity.
The 0.2mm TDI has the same sensitivity per pixel
as a 0.4mm LDA.

The Harrier XTI9080X series of time delayed
integration (TDI) cameras provide highsensitivity and resolution compared to
traditional linear diode arrays.
Theaccumulation of signal by combining 8 rows ofpixels increases signal, decreases signal tonoise ratios, providing higher sensitivity that

Principal of operation
In the operation of both traditional Linear Diode Array (LDA) and TDI detectors, objects must
be moving relative to the detectors. In an LDA, a single line of diodes collect signal. Once theobject has past the diode line, no more signal is collected. A TDI device has multiple diodelines and the signal for each line can be passed to the next line. As the object passes overeach line, each line collects signal and then passes the signal to the following line. After theobject passes the final line, the full integrated signal is read out. When the TDI device is
synchronized to the moving object, an image with higher resolution at lower light level isachieved. As a result, signal-to-noise ratio in TDI camera is much higher than that in a linescan camera.

X-Scan Imaging housings are available in two form factors. The DR housing is a low profile,wider detector to fit under conveyor systems or other tight spaces. The DS housing is a taller,narrower profile. The standard X-Scan Imaging detectors, Single Energy, Dual Energy, andCMOS TDI all share the same mounting hole pattern.
