摘要
研制成功了128×1元GaAs/AlGaAs多量子阱扫描型红外焦平面(FPAs),器件的响应率达到RP=2.02×106V/W,截止波长为λc=8.6μm.根据常规的黑体探测率定义,得到器件的黑体探测率为Db*=2.37×109cm·Hz1/2/W,并最终获得了清晰的室温物体残留热像图.
A scanning infrared FPA of 128×1 multiple quantum wells(MQW) was developed. Responsivity R P =2.02×10 6V/W was obtained with the cut off wavelength λ c =8.6 μm. By the typical blackbody detectivity definition, the detectivity is D b *=2.37×10 9cm·Hz 1/2 /W. Finally, a distinguished remnant thermal image of a room temperature body was obtained.
