Design of Image Acquisition Circuit for Pixel Coupled Infrared Polarization Camera Based on FPGA

The lack of integrated acquisition circuits in pixel coupled infrared polarization cameras restricts the development and application of polarization technology. FPGA has the ability of parallel processing, which can meet the needs of simultaneous transmission and processing of multi-channel data, with high data throughput and fast processing speed. At the same time, there are a large number and diverse types of IO ports that can be combined with different interface chips to design multiple types of interface circuits and achieve various circuit functions. In the process of circuit design, the idea of modular design is adopted. The circuit schematic diagram of the module is designed according to the Functional requirement, and the PCB is drawn according to the schematic diagram. Finally, the finished circuit board is produced. The functionality of the circuit board was experimentally verified using the approach of modular verification followed by overall verification. Through verification, the circuit board produced can meet the function of pixel coupled infrared polarization camera image acquisition and display. The design concept of this article has reference significance for the production of other related circuits.
