摘要
分光计在大学物理实验中用来测三棱镜的顶角、折射率以及光波波长或者光栅常数等物理量,掌握和使用分光计是一个重要的实验技能,由于调节内容较多,快速调出反射镜两个面反射的十字像一直是分光计实验中的难点.本文就此设计了基于CCD成像的系统使反射的十字像能够成像在电脑显示器上,扩大视野,便于调整,在给学生讲解演示中效果好.
Spectrometer is useful to measure the physical quantities such as the angle of prism, refractive index, wavelength, grating constants, and etc. So the mastery of spectrometer is an important experimental skill. But it is difficult to adjust the two cross figures reflected by the reflector congruously in a short time because of too many adjustable contents. In this paper, we have designed a CCD imaging system to image two cross figures on the computer display, by which the vision is enlarged and the adjustment become more easy. As a demonstration ex periment, it is proved to be very fine for students in practice.
