A small infrared imaging system

Abstract

The invention discloses a small-sized infrared imaging system. The system gathers the infrared radiation emitted by a target object onto an infrared focal plane array by means of an infrared lens working in a specific band. The focal plane array generates a response signal to the infrared radiation, and a readout circuit converts the The response signal is output to the signal processing board, and the signal processing board performs a series of signal processing on it, and finally synthesizes a standard video signal and sends it to the display screen for display. The system can perceive, collect, process, display and store the infrared radiation emitted by the target in real time. In terms of signal processing, the present invention proposes a new space-time domain combined infrared image filtering and noise reduction method. At the same time, the system of the present invention has the advantages of low power consumption, small size, light weight, low cost and high reliability. advantage. Based on the above advantages, the application of the present invention in the military field, commercial field and industrial field has broad prospects.

Problems solved by technology

However, in these systems, DSP and FPGA based on bus time-division multiplexing need to frequently switch the control rights to the memory, which will inevitably reduce the data transmission efficiency of the entire system, increase the complexity of system logic control, and non-system design and application. bring a lot of inconvenience

More importantly, the circuit using the DSP+FPGA architecture is relatively large, and it is difficult to meet the requirements of system miniaturization
