平板剪切干涉法检验激光准直性的改进

An Improvement to the Plate Shearing Interferometry for Testing Laser Collimation

本文提出了利用平板剪切干涉法检验激光束准直性的一种改进方案。以两组干涉条纹的平行作为准直性判据,既简化了检测过程,又可使检验灵敏度提高一倍。

An improved approach for testing laser collimation by using plate shearing interferometry is put forward in the paper.Taking the parallelism of twe groups of interference fringe as the criterion of collimation, thus not only simplifies the testing process, but also raises the testing seisitivity.
