摘要An electronics system was developed according to the low noise requirement of FOT X-ray detector in this paper. The electronics system consists of an analog drive circuit, a front end processing circuit and a digital signal processing circuit which is based on field programmable gate array (FPGA). The performance of FOT X-ray detector was evaluated on the X-ray imaging platform. The overall system gain is 0.168 6 DN/e-, and the linear operating range of the detector is 0-154 μGy. When the cooling temperature reaches -20 , the dark current noise is 0.037 e-/(pixel·s) and the read noise is 10.9 e-. The intrinsic spatial resolution of the detector is 16 lp/mm. The results indicate that the designed read-out electronics system meets the requirements of high resolution X-ray detector. ©, 2015, Atomic Energy Press. All right reserved.
