Abstract
The infrared focus plane array device is a new generational infrared detector which has
the function of both radiate sensitivity and signal process. The imaging system with IRFPA
has many advantages such as: the reform from optical and mechanical imaging to electrical
signal process imaging is achieved; The cubage, quality and power of imaging system are
greatly reduced; The area of speciality involved by system is limited, the mechanical
complexity is greatly reduced and reliability is observably improved. The frequency of frame
in system is very high, so delay of information is greatly reduced and this is adapt the
requirement of obtaining image information in high speed and ultra-high speed guided missile
weaponry system. The sensitivity of system is greatly improved, SNR can theoretically be
increased N times, where N is the amount of detector. Because the pretreatment circuit
(export circuit, such D memory, CMOS multi-channel transmission device and so on) is
encapsulated on chip, the amount of signal wire is effectively decreased, so the condition of
process for the whole detector is greatly predigested and the reliability of system is
observably
