本文介绍用全息干涉法测量大块光学玻璃均匀性的光学系统,对准直系统的要求作了全面分析,在实验技术中提出利用莫尔条纹使反射纹变细。最后给出实验结果。
In this paper, an optical system for measuring the uniformity of large optical glass by holographic interferometry is introduced. The requirements of the collimation system are analyzed comprehensively. In the experimental technique, the use of moire fringes is proposed to make the reflective lines thinner. Finally, the experimental results are given.
