本文发展了一种用空间非相干光记录漫射物体的彩虹全息图,并用白光再现的技术.实验结果表明,这种方法大大抑制了全息像的噪声,改善了全息像质.因此,这是一种减弱散斑的简单而有效的方法.

An incoherent rainbow holography technique has been developed. We recorded rainbow hologram of a diffuse object with spatial incoherent light and reconstructed it with white light. The experimental results show that this method substantially suppresses the noise of hologram and improves the holographic image quality. Therefore, this is a simple and effective technique for speckle reduction.
