摘　　要：受当前实验教学设备集成化的影响,很多实验仪器都被做成了"黑箱子",使得实验教学难以达到预期的工程训练目标。该文以"迈克尔逊干涉仪实验"为对象,将其扩展为"基于迈克尔逊干涉仪的波长计设计与实现实验",并提出实验设计方案、系统定标方法和未知激光波长反演算法,并对两个已知输出波长的激光波长做了反演测量,测量结果与厂家标称值接近。该实验在学生操作过程中,实验系统由学生根据实验原理自助搭建,从而将实验原理、系统搭建、数据测量、数据分析和报告撰写融为一体,践行"新工科"人才培养理念,提高"新工科"人才培养目标的达成度。Due to the integration of the current experimental teaching equipment, many experimental instruments are made into a“black box”, which makes it difficult for the experimental teaching to achieve the expected goal of engineering training. In this paper,the experiment of the Michelson interferometer is extended to “the design and implementation experiment of wavelength meter based on Michelson interferometer”. The experimental design scheme, system calibration method and unknown laser wavelength inversion algorithm are proposed. The laser wavelengths of two known output wavelengths are measured by inversion. The measurement results are close to the nominal value. In the process of students’ operation, the experimental system is built by students themselves according to the experimental principle, which integrates the experimental principle, system construction, data measurement, data analysis and report writing, practices the “new engineering” talent training concept, and helps to achieve the “new engineering” talent training goal.
