IMAGE SENSOR
Flat panel sensor
C9732DK
Large area/soft X-ray imaging, high resolution
Flat panel sensor C9732DK is two-dimensional CMOS image sensor module designed for X-ray imaging which requires high resolution,
large area and wide dynamic range. A target material of X-ray source and X-ray energy adequate for the sensor is Mo and 17 keV. The
device shape is thin cassette which incorporate on-chip high-resolution scintillator and a control board. An on-board USB2.0 interface can
realize fast data transfer with C9732DK.

Block diagram
C9732DK is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board also
has 8 charge-sensitive amplifier arrays each having 300 channel amplifiers with a horizontal shift register. Analog video signals
are amplified as the charge on each video line by 2400 ch charge amplifiers with CDS (Correlated Double Sampling) circuits, and
are output is obtained from each of 8 amplifier arrays. The control board converts the analog video signal into a 14-bit digital
signal and outputs it to an PC through the USB2.0 interface.
