摘　　要：针对SGP-2A型偏振光实验系统在使用过程中存在精度低、实验效率低下和表现力弱等不足,对以微处理器STC12C5A60S2为核心的系统进行了改进.改进后的系统采用模块化设计,可根据交互指令实现数据的采集、处理和显示自动化,提高了系统的测量精度、实验效率、数据表现力和便携性,满足了实验教学和课堂演示需求.As the SGP-2A-type polarization optics experiment system has many disadvantages, such as low precision, low efficiency and weak performance, the paper provided an improved system based on the microprocessor of STC12C5A60S2. The improved system adopted modular design, real- ized automated data collection, processing and display. It improved the measurement accuracy, test efficiency, data expressiveness and portability to better meet the needs of teaching in the experiment and presentations in class.
