Influence of Digital Holograph Zoom on DMD Reconstruction Display
全息图像缩放对数字微镜重建显示的影响研究

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.
