  • Aiming at the slow response speed, low sensitivity, poor vibration resistance of existing Fourier transform infrared spectrum telemetry, a new method was put forward with static solid wedge interference as the core. UL 371-042-04 uncooled infrared focal plane array detector was selected as the core component of interference signal detection. Driving circuit was designed based on the analysis of the basic theory of static solid wedge interference and detector performance. FPGA as the main part of sequential control, designed input and verified simulation of the work timing of detector with Verilog hardware description language programming in Xilinx ISE 12.4 development environment. It can make the interference signal go through high-speed AD sampling and FPGA outside enlarge SRAM cache, the processed signals are sent to PC LABVIEW for data processing and imaging via USB finally. Kealized the infrared wavelengths of static solid wedge interference signal spectrum imaging by simulating and experimenting to verify its feasibility, provided preparation for further study of interferometric imaging spectrometer imaging technology.
