Matlab的无透镜傅里叶全息技术

Technology of Non-lens FFT Holography Used Matlab

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。

Nolens Fourier transform holography with object field reconstruction process is simple, fast, realtime characteristics,while object light and reference light intensity ratio affect the reproduction image quality and clarity, with the aid of MATLAB simulation of off axis Fresnel digital hologram and reconstructed image, found that when the object light and reference light intensity ratio are 1:1, the reconstruction of the hologram is the clearest; at the same time,by building experimental platform to verify the reference object ratio between the 1:1 to 1:3, ideal results were gained. Experiment and simulation coincide.
