摘　　要：焦平面阵列是光学读出非制冷红外成像系统的重要部分。在理论分析的基础上设计了一个显微数字全息系统,测量了一种FPA的热机械灵敏度,结果为0.199deg/K。实验还发现FPA反光板上不同位置处热机械灵敏度是不同的,实验给出了热机械灵敏度随到反光板固定端距离的变化函数关系式。The focal plane array is the key part of optical readout uncooled infrared imaging system. Based on theoretical analysis,a digital holographic microscopy system was designed for measuring the FPA thermo-mechanical sensitivity,and the experimental result was 0. 199 deg/K. Experiment also shown that the sensitivity on different position of reflector was not the same,and gave out the function of thermo-mechanical sensitivity changing curve based on the distance to the fixed end.
