拓展全息照相实验内容的教学实践

A Teaching Practice to Enrich the Holography Experiment

针对实验教学中存在的问题,以"全息实验"教学为例,进行了"教师启发,学生探究"模式的教学实践.即在原实验内容的基础上,引导同学进行"明室"全息、多次曝光拍摄、漫反射和透射全息以及全息图的复制等简单有趣的实验,使之从中体会到探索之妙,丰富其课内外实验的教学内容和方法,提高教育教学的效果和实验室教学的效益.

To settle the existing problems in college experimental courses,a practice of 'inspired by instructor,inquired by students' is explored in this article with 'holographic experiment' as a teaching example.In the teaching,students are guided to explore those simple and interesting experiments such as multi-exposure,diffusion or transmission holography,the duplication of holograms,and holography in a normally lighted room and find the pleasure of research.It is believed that the practice can enrich the content of experiment course and improve the effect of experiment teaching.
