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。 Aiming at the problem that the IRFPA imaging system has a narrow dynamic range due to the integral time being fixed, a method of adjusting the dynamic range of the IRFPA imaging system based on integral time is proposed. Using this method, an IRFPA imaging system with variable integration time is designed. Finally, the experimental results are given. The results show that the proposed method is feasible and can effectively expand the dynamic range of IRFPA imaging system.
