| Abstract: | In order to improve the imaging quality of infrared focal plane array ( IRFPA ) detectors, an infrared video image digital processing system with digital signal processor as the core was proposed. The hardware block diagram and algorithm realization wereintroduced, and the system functions and several key techniques were analyzed. The field test and measurement show that the integration time is adjustable from 0. 5 ms to 5 ms, the frame frequency is adjustable from 25 Hz to 5 Hz and the processing delay of the system is not more than 2 ms which meets the real-time and reliability requirements. The system can be used as the post-processing circuit in several types of military infrared detectors. |
