摘要

在分析法国ULiS公司生产的320×240长波红外非制冷微测辐射热计焦平面阵列探测器UL01011技术参数的基础上,论述了微测辐射热计非制冷红外焦平面热像仪温度控制的必要性,指出了温度控制设计的实质.并讨论了单片机、线性模式单芯片热电制冷器控制器和开关模式单芯片热电制冷器控制器温控方案的优缺点.提出了使用AD公司生产的全新单芯片热电制冷器控制器ADN8830的温控设计方案,以该芯片为核心设计出适合320×240长波红外非制冷微测辐射热计焦平面阵列探测器UL01011的温度控制电路,该电路能够把焦平面阵列温度变化控制在30±0.01℃范围内,使探测器工作在最佳温度.该方案功耗低、效率高、体积小,是一种较好的温控设计方案.

Abstract

On the basis of analysis of the technical specifications of the 320x240 long wavelength infrared uncooled microbolometer detector developed by ULIS Corporation of France,the necessity of temperature controlling for microbolometer uncooled focal plane arrays thermal camera is discussed,and the essential aspect of design of temperature controlling is presented.The merits of temperature controlling schematic by single chip microcomputer, liner mode monolithic thermoelectric cooler controller and switch mode monolithic thermoelectric cooler controller are discussed.A appropriate temperature controlling circuit for the 320×240 long wavelength infrared CMOS uncooled integrated microbolometer detector is developed by a single chip monolithic thermoelectric cooller controller, named ADN8830, produced by Analog Devices Inc.,and the temperature controlling circuit can keep the temperature change of the uncooled focal plane array detector in 30±0.01 ℃ so that the uncooled focal plane array detector work in the range of the most optimized temperature. This is a better scheme of temperature controlling for its high efficiency, low power and compact size.
