基于积分时间的IRFPA成像系统动态范围的调整

Dynamic Range Adjustment of IRFPA Imaging System Based on Integral Time

针对目前一些红外焦平面阵列(IRFPA)成像系统由于积分时间固定导致动态范围较窄的问题,提出了一种基于积分时间的调整IRFPA成像系统动态范围的方法。采用此方法,设计了一种积分时间可变的IRFPA成像系统,最后给出实验结果。结果证明所提出的方法是可行的,能有效地扩大IRFPA成像系统的动态范围。

A method for adjusting the dynamic range of infrared focal plane array（IRFPA） imaging system is proposed based on integral time.Using this method,an IRFPA imaging system is designed based on variable integral time,and the experimental results are presented.Results prove that the proposed method is feasible and can effectively expand the narrow dynamic range caused by fixed integration time.
