Development and testing of a flexible image capture system based on domestic radiation-hardened electronic components

The aim of the work is to create a universal flexible image capture system required for recording images of various wavelength ranges in space scientific equipment. The main problem of implementing such a system is the limited bandwidth of the channel for forming a full image frame. To solve this problem, the authors designed an algorithm based on the process of recording a frame with accumulation, that allowed to form a full image frame using several real frames with reduced number of pixels got with the matrix photodetector. The result of the work is a system built on the principle of a tiered design, having small dimensions, high noise immunity, high reliability and resistance to external factors, as well as full support for the FMU (Flexible Microcontroller Unit) core. Russian radiation-resistant electronic components were used as materials. The main HDL (Hardware Description Language) modules were optimized to reduce the number of gates and to adapt for household FPGAs. Parameters comparison of the image capture module implementation on various FPGAs is given in this article. This system can be used both in space equipment (using radiation-resistant electronic components) and for household or educational use (implementing the system on household components). The system also has a number of program-controlled parameters that allow to configure the matrix system registers. For capturing and processing images was created software on a personal computer. The results of debugging the system and examples of test shots are given.
