在刀口滤波光学读出方法的基础上,讨论了反光板弯曲的情况下,刀口滤波方法的光学检测灵敏度与反光板长度之间的关系.分析表明,在反光板曲率半径一定的情况下,光学检测灵敏度首先随着反光板长度的增加而增大,达到最大值后随着反光板长度的增加而减小.对于不同曲率半径和长度的反光板,分析给出反光板长度L和曲率半径R在满足L~2/R=λ(λ为照明光波长)时,光学检测灵敏度达到最大值.实验测量了已制作的像素尺寸分别为200μm,120μm和60μmFPA的光学检测灵敏度,其实验结果和理论分析一致.

Based on the optical readout method with knife edge filter, the relationship between the optical detection sensitivity and reflector length was discussed under the circumstance that the reflector was bent.Analysis indicates that the optical sensitivity increases with the reflector's lengthening at first, then it reaches a maximum value, and then it decreases as the reflector continues to lengthen.For the reflectors with different curvature radii and lengths, analysis shows that the sensitivity will reach a maximum value when the expression L~2/R = λ(L is length of reflector, R is curvature of the reflector, A is wavelength of illumination light) is satisfied.The optical detection sensitivities of the fabricated FPAs with different pixel sizes as 200μm, 120μm and 60μm were obtained experimentally.The result coincides with the theoretical analysis.
