Abstract

The target detection ability of external thermal imaging system is affected by many factors, including the source and influence of system heterogeneity, the digital enhancement mechanism of infrared imaging, the realizability and real-time of system super-resolution and so on. The infrared focal plane detector integrates focal plane daylighting array, signal readout circuit, temperature control circuit, timing control circuit, etc. requires the external supply of appropriate driving voltage and digital timing signal to work normally. Because the infrared detector belongs to the front-end device of the system with high sensitivity, its requirements for working voltage and digital timing are also relatively strict. The quality of driving signal determines whether the infrared detector can work in the best state, so that the following image processing circuit can get the best original infrared image. By studying the imaging principle of uncooled focal plane detector, this paper puts forward the key factors affecting the performance of infrared image, and puts forward hardware based low-noise bias voltage signal generation technology, which improves the intelligent level of the system under the condition of ensuring the stability of the system.
