摘要
介绍了一种以激光为光源对透过率进行测量的学生实验仪组成原理,实验仪主要由硬件和软件两部分组成。考虑到实验教学的特点,仪器采用模块化设计,以便于学生灵活操作,尽可能多地为学生提供动手的机会。描述了各个硬件模块的设计原理,重点是光电信号处理部分的各个电路模块的设计,阐明了激光调制光源等关键光电器件的选择方法。实测结果证明,整个仪器可以满足透过率测量要求。
This article introduced a kind of experimental instrumentation which is used to research and measure the transmittance with a laser light source.The experimental instrument is mainly composed of two parts: the hardware and software.Taking into account the characteristics of experiment and teaching,the instrument is of modular design in order to make the operation more flexible and convenient and provide the students more opportunity of practice as much as possible.The design principle of each hardware was d...
