摘　　要：介绍微型计算机自动控制技术在光谱自动测量中的应用.利用微型计算机接口技术、光电转换技术,由微机控制步进电机,步进电机带动光栅单色仪传动,在可见光(380～780nm)范围内逐点扫描得到对应于各波长位置的相对光强度分布值,实现对光谱的自动测量.其中微机接口的软、硬件设计是重点.The application of personal computer control technique for automatic measurement of spectrum was introduced.By using the interfacing technique of personal computer and optical-electric coversion technology,the step motor,controlled by microcomputer is used to drive monochromator and scan light in the scope of visible light pointwisely(380～780nm),the distribution values of luminous intensity in correspondence with each wavelength location can be obtained.so the spectrum is measured automatlcally by computer.
