电视技术在微小尺寸测量中的应用
Application of TV Technique in the Measurement of Micro-Dimension
【摘要】 本文介绍由光学显微镜、电视摄象系统和微处理机组合而成的BCM5-1T型电视测量显微镜。采用高频脉冲计数、光标测量区域指定、自动阈值、系统非线性的计算机数字补偿等技术措施,实现了在较大视场范围内微小尺寸的高精确度测量。
【Abstract】 -This paper presents a TV measuring microscope of Model BCM5-1T which consists mainly of an optical microscope, a TV camera system and a microprocessor. Some techniques are used in this apparatus, such as high-frequency pulse count, measuring range indication by cursor, auto-threshold as well as digital nonlinea-rity compensation by computer. So the micro-dimensional measurement on a large vie-wing field can be realized with high accuracy.
