Holographically amplified interferometry with coherent fringe projection for the oil on the water remote sensing and characterization

摘要

We suggest combining several optical methods of remote sensing and characterization of crude oil films and emulsions: coherent fringe projection illumination (CFP), holographic in-line interferometry (HILI). Combined methods of CFP and HILI are described in the frame of coherent superposition of partial interference patterns. Moreover, we evaluated different alternative schemes of interferometry with holographic recording and preliminary holographic amplification in photorefractive crystals. Holographic amplification of weak images without phase distortions is possible in a special mode of holographic recording in photorefractive crystals.
