Speckle reduction of rainbow hologram by incoherent holographic technique
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.
