The Integrated Photoelectric Photometer System Used with A Microcomputer

The design ideas,structure and characteristics of the photometer attached to the 100-cm telescope arc described in this paper.The instrument is a DC integrated photoelectric photometer system.The integrating function and the integration time can be chosen freely.There is a microcomputer with a set of excellent software,which can be used to make real time collections and data reduction and observations.There are two colour systems in the photometer,Johnson's UBV system and Stromgren uvby system,in which an EMI 6256B photomultiplier tube is used.
