【摘要】No-lens Fourier transform holography with object field reconstruction process is simple, fast, real-time characteristics, while object light and reference light intensity ratio affect the reproduction image quality and clarity, with the aid of MATLAB simu-lation of off axis Fresnel digital hologram and reconstructed image, found that when the object light and reference light intensity ra-tio are 1:1, the reconstruction of the hologram is the clearest;at the same time ,by building experimental platform to verify the refer-ence object ratio between the 1:1 to 1:3 , ideal results were gained. Experiment and simulation coincide.%无透镜傅里叶变换全息术具有物场重建过程简单、快速、实时的特性,而物光与参考光的光强比影响再现像的质量和清晰度,借助MATLAB仿真模拟离轴菲涅耳数字全息图和再现像,发现当物光与参考光的光强比为1:1时,所拍摄的全息图重构像最清晰;同时搭建实验平台验证了物参比在1:1到1:3之间效果均较理想,实验与仿真相吻合. 【总页数】3页(142-144)
