Abstract

We demonstrate full-color imaging through a turbid medium by use of photorefractive coherence gating and a technique to separate the recording space of each color from those of the other colors. We found that the recording spaces must be separate when a multicolor image is recorded in a photorefractive crystal to prevent the interference of the holograms with one another. For full-color imaging we used a He–Cd white-light laser, which is compact and useful for full-color holography. Full-color-image retrieval is demonstrated through five mean free paths of a turbid medium.
