Verification of a Readout Design for Multiple Energy Discrimination working in Single Photon Processing Pixel Array

The improvements in CMOS technology can be used for increasing the range of applications for X-ray imaging sensors. This paper shows measurement results for multiple energy discrimination in single photon processing pixel array. The measurement used technique demonstrates colour resolution based on colour sub-sampling with intensity biasing for three-level energy discrimination that corresponds to colour imaging systems for visible light with R, G, and B colour components. It is the result of balancing the circuit complexity and the image quality. The coloured X-ray could be used to expose dense object and projecting the colour of depth layers without fragment the sample, it also useful to develop X-ray spectroscopy and florescence systems realistic radiology for both materials and biological substances
