摘要
根据人眼对数字微镜器件成像的响应性质,给出了数字微镜器件重建场的强度表达式.当CCD的面元尺寸与数字微镜器件的镜元尺寸不相等时,在数字微镜器件重建显示系统中将引起数字全息图像的缩放.基于傅里叶光学理论,导出了缩放后数字全息图数字微镜器件重建像的尺寸和中心位置与重建参量的关系.通过理论模拟和数字微镜器件重建显示实验,对分析结果进行了实验验证.
The intensity expression of DMD reconstruction field was educed based on ocular response character for DMD imaging. When there are different unit sizes between CCD and DMD, digital hologram zoom will be caused during the reconstruction display. According to Fourier optical theory, the relationship was obtained between the size and center position of DMD reconstruction object from zoomed hologram and the reconstruction parameter. And, simulation experiment and DMD reconstruction experiment were designed to validate the analytic results.
