【摘要】 本文介绍GCCS-89型r相机智能化数据采集接口。它以PC/286或PC/386微机为基础,有帧模式、表模式、多门控、缓冲门控等多种数据采集方式,采集条件的设定及工作状态的转换全由程序控制。它能与各种Anger相机配接,具有死时间短(<2μs)非线性失真小(<2.5％)的特点。更多还原

【Abstract】 The data acquisition interface of GCCS-89 introduced in the paper is program-controlled. I,t is based on PC/286 PC/386 microcomputer and supports all acquisition modes including frame mode, list mode gated mode and buffered-beat multi-gated acquisition. It can be connected with various Anger cameras. By using high precision, high speed A/D converter and slide technique, nonlinearity of the interface is made less than 2. 5% , and dead-time is cut to below 2μs.更多还原
