一、引 言 精密定量检测大口径光学玻璃的均匀性是研制和生产大口径光学仪器的前提.我国大多数工厂和研究单位,目前仍用星点法与鉴别率法进行定性检验,不能精确定量.为提高光测水平,近年来开始用全息照相技术精密检测大块玻璃的光学均匀性的研究.我们和许多兄弟单位协作研制成 I. INTRODUCTION Precise and quantitative detection of the uniformity of large-diameter optical glass is the prerequisite for the development and production of large-caliber optical instruments.Most factories and research institutes in our country still use the method of the constellation and the identification rate to conduct qualitative tests and can not accurately quantify them. In order to improve the level of optical measurement, in recent years, holographic photography has been used to precisely examine the optical homogeneity of bulk glass.
