Infrared focal plane array image-forming demonstration system

Abstract

The invention discloses an infrared focal plane array imaging demonstrating system. Said system comprises an infrared radiating resource, infrared optical lens, an infrared focal plane detector, a programmable infrared detector driver, a high-speed interface, a high-speed data collecting card, a main processing unit and a high-functional computer. The infrared radiation is focalize on the infrared focal plane detector via the infrared optical lens; each unit on the infrared focal plane detector can convert the infrared radiating signal into electrical signal driven by driving and offset signals provided by the programmable infrared detector driver; clock and triggering signal needed by the programmable infrared detector driver is set by program programming of the high-functional computer which is transmitted to the programmable infrared detector driver by the main processing unit, high-speed data collecting card and high-speed interface. This invention enables designing stuff intuitively observe and evaluate the real imaging effect of the designed system and arithmetic and timely rectify and check the design and arithmetic, avoiding all sorts of troubles during process of system debugging.

Description

a technical field [0001] The invention belongs to infrared thermal imager technology, in particular to an infrared focal plane array imaging demonstration system. Two background technology [0002] The development of the image processing board is the key to the design of the infrared thermal imager. At present, researchers of infrared thermal imaging cameras and image processing algorithms at home and abroad have proposed a variety of algorithms, but their practicability, real-time performance and application range need to be verified by research, and there is no such corresponding algorithm evaluation demonstration in China. The system is simulated and evaluated. The existing method is to make multiple versions of the hardware circuit of the whole system, and repeatedly debug, revise and verify. The development cycle is long, the cost is expensive, and it is often unknown which part has a problem during the debugging process. In 2002, the article of MichaelA.Soel et al in...
