摘　　要：从理论上分析了在模压三维全息图母版的记录光路中，为消除或减小像散和像场弯曲以及扩展照明光源产生的像模糊所应采取的参数设置。试验结果表明用此方法制作的模压三维全息图即使在漫射照明光下亦能呈现出清晰、明亮的图像。A theoretical analysis is presented for selecting optimal parameters in recordinggeometries of embossing master holograms to eliminate astigInatism alld field curvature ofthe reconstructed images, and the image blur caused by extended illuminating light source.The experhoental result shows that the embossed hologram with 3D image made using themethod reconstructs bright image with high resolution even under diffused illumination.
