项目摘要

The present work is concerned with a construction of a real-time phase conjugate interferometer using dye-doped polymer films and its evaluation. This interferometer consists of an Ar-ion laser as a light source, an interferometer of degenerate four-wave mixing (DFWM) configuration. which uses a phase conjugator, and a sensing part. The whole system is set on a vibration-isolated optical table. This phase conjugate interferometer has two kinds of functions : a real-time sensing of the phase difference and amplitude difference between two objects or in temporal variation in an object. Owing to both functions, an edge enhancement, a defect detection and so on also can be performed in addition to traditional real-time interferometry.In order to make possible such operations, the requirements for the dye-doped film. are : (1) it can generate phase conjugate waves due to not only the DFWM process but also a recorded interference fringe without development and (2) the polarization states of the former and latter phase conjugate signals are the same as those of the input probe wave and the. read-out pump wave, respectively.A baked erythrosin-B-doped PVA film was suitable for this purpose. The rising time of the phase conjugate signal due to the DFWM process was-lmsec., and the refrectivity of-1% was. obtained at 515nm for the pump power of-1w/cm^2. The films prepared in our laboratory had 5cm x 10cm in size and 50 mu m-100 um m in thickness.This phase conjugate interferometer was verified to work well. With a methyl-orange doped PVA film as a phase conjugator a. novelty. filtering can be performed.

目前的工作与使用染料掺杂的聚合物膜及其评估的实时相结合干涉仪的构建有关。该干涉仪由AR-ION激光作为光源组成，该光源是退化的四波混合（DFWM）配置的干涉仪。使用相结合器和感应部分。整个系统设置在振动式光学表上。该相结合干涉仪具有两种功能：对两个对象之间的相位差和振幅差的实时感测或对象中的时间变化。由于这两个功能，边缘增强，缺陷检测等等，除了传统的实时干涉法之外，还可以执行。为：（1）它不仅可以由于DFWM过程，而且还可以产生相结合波，而且还可以产生没有发育的记录的干涉条纹，并且（2）前者和后者相结合信号的极化状态与输入探针波和后者的偶联信号相同。读出的泵浦波。烤红细胞素B的PVA膜适合此目的。由于DFWM工艺引起的相结合信号的上升时间为lmsec，而1％的倒置性为1％。以1W/cm^2的泵功率在515nm处获得。在我们实验室制备的膜的尺寸为5厘米x 10厘米，厚度为50 m-100 um m。这相结合干涉仪已被验证可正常工作。用甲基橙色掺杂的PVA膜作为相结合a。新奇。可以执行过滤。
