Abstract

Coherent amplification of images by two-wave mixing in photorefractive crystals is examined with attention given to processing in the Fourier domain. It is shown that the gain that is experienced as the probe image traverses the crystal is approximately uniform across the image. The gain can be expressed as a function of the average probe to pump intensity ratio. Experimental verification is given to support the theory.

摘要

研究了光折变晶体中通过两波混频对图像进行相干放大，并关注了傅里叶域中的处理。结果表明，当探测图像穿过晶体时所经历的增益在整个图像上大致均匀。增益可以表示为探测光与泵浦光平均强度比的函数。给出了实验验证以支持该理论。
