摘　　要：像面数字全息检测是相干光成像的一种重要应用。然而,由于相干传递函数的空间滤波作用,故当成像系统出射光瞳尺寸较小时,电荷耦合器件(CCD)不能探测到完整的像光场。同时,利用目前流行的只能计算像光场振幅分布的理论,不能重建便于光学检测的具有振幅和相位分布的像光场。基于相干光成像理论的分析,提出了一种设计特定照明物光的方法,让光学系统能够对物平面检测区完整成像。将物体照明光的全息图与所提方法结合,可以重建便于实际检测的理想像光场。Image plane digital holographic detection is an important application of coherent light imaging.However,due to the spatial filtering of coherent transfer function,charge coupled device(CCD)cannot detect the complete image light field when the exit pupil size of the imaging system is small.Moreover,using the current popular theory that the amplitude distribution of the image light field can only be calculated,the image light field with amplitude and phase distribution which is convenient for optical detection can not be reconstructed.A method of designing specific illumination light is proposed based on the analysis of coherent light imaging theory.Using the proposed method,the object plane detection area can be complete imaging by optical system.By combining the hologram of object illumination light with the proposed method,the ideal image light field which is convenient for practical detection can be reconstructed.
