一、引言在天文光电测光领域内,需要把测定天体亮度或位置的微弱信号,变成光电信号,经放大、整形后进行记录。长期以来均采用直流放大方法,这种方法特点是电路简单,但由于直流法测量中的直流放大器增益不稳定性和零点漂移等问题,影响了观测精度。近年来,由于计算机技术的发展,促进了实测天文的进步,有可能对每一个光子事件进行记录。我们研制的光电测光 I. INTRODUCTION In the field of astronomical photometric photometry, the weak signals for measuring the brightness or position of a celestial body need to be changed into optical signals and recorded after amplification and shaping. DC method has long been used, this method is characterized by a simple circuit, but due to DC method DC gain gain uncertainty and zero drift and other issues, affecting the observation accuracy. In recent years, due to the development of computer technology, the progress of the astronomical survey has been promoted and it is possible to record every photon event. We developed the photoelectric photometry
