摘　　要：讨论现有棱镜摄谱仪成像方法的不足,介绍一种用数码照相CCD成像技术改造棱镜摄谱仪和计算机程序处理进行光谱分析的方法;本设计的棱镜摄谱装置能够清晰地拍摄标准光谱与待测光谱,可以通过数码照相机二合一功能或者计算机程序处理将两者成像在一张图片上,它既可以从各条彩色谱线的颜色上用目测分辨出其大致波长值,又方便于两者之间的比较与精确测量;用该技术改造后的棱镜摄谱仪成像比较直观,清晰度高,花费低廉,结构简单、紧凑,在工矿企业和高校物理实验中有较好的实用价值。Existing imaging method of prism spectrograph is discussed and an imaging technology, which uses digital camera CCD to improve prism spectrograph, and a spectrum analysis method based on computer program are introduced. The prism spectrograph designed with this method can shoot standard spectrum and spectrum being measured; these two spectra can be imaged on one picture using the two-in-one function of digital camera or computer program processing. The wavelength can not only be distinguished by eyes from the color spectrum, but also be compared and measured precisely and conveniently. More intuitive and clearer images can be obtained using the improved prism spectrograph, which features low cost, simple, compact structure and has good practical value in industries and college physics experiments.
