摘要 智能数字毫伏表以单片机AT89S52为控制器,可对光学实验中的光强大小进行测量,并可对实验数据进行分析、处理,帮助验证相关实验原理。以光学单缝衍射实验为例,讨论数据的处理过程,并与理论值进行比较。本仪器操作简单,精度高,已应用在单缝衍射、偏振光、双缝干涉、杨氏模量测试等实验中。 Intelligent-digital millivoltmeter takes SCM AT89S52 as kernel. It can measure the intensity of light, as well as analyze and manipulate experiment data. The results can help experimenter to verify the experimental theory. Taking the case of single-slit diffraction experiment, the paper discussed the data processing and compared the data to theoretical value. The high precision apparatus is easy to manipulate, and has been applied in the single-slit diffraction experiment, polarized light experiment, double-slit interference experiment, Young' s modulus of elasticity testing experiment, etc.
