点光源照射下彩色图像随机相位编码的实现

Random phase encoding achievement of color images under spotlight illumination

为了实现对彩色图像的单随机相位编码,根据随机相位编码原理,提出采用单色点光源照射系统结合波长多路技术,实现了对组成彩色图像的三基色图像进行随机相位编码。理论分析和数值模拟显示,采用单色点光源照射系统,对彩色图像进行随机相位编码是可行的;同时由于系统装置的减少,有效地减少了由于随机相位掩膜所引起的相应光能损失和图像噪声。结果表明,这种方法在追求彩色还原度高的场合具有实用价值。

In order to achieve single random phase encoding of color images, based on the principle of random phase encoding and multi-wavelength technology, the random phase encoding of trichromatic images was realized. Theoretical analysis and digital simulation results show that using spotlight illumination systems to realize random phase encoding of color images is feasible. As the installations are reduced, the light energy losses and the corresponding image noise from random phase mask is effectively reduced.
