摘　　要：为了在光电基本理论、实践环节中更好地培养学生分析问题和解决问题的能力,在光电信息科学与工程专业实验教学中加入超声波测距、激光脉冲测距和激光相位测距系统设计等实验内容。学生通过3个测距实验的学习,更好地掌握光通信系统技术、激光发送和接收器件的工作机理,以及光电工程电路设计与实现方法。通过测距系统的设计与实验,学生的综合应用、设计能力都有较大提高。In order to cultivate students’ ability to analyze and solve problems better in the basic theory and practice of optoelectronics, experimental contents such as ultrasonic ranging, laser pulse ranging and laser phase ranging system design are added to the experimental teaching of Optoelectronics and Information Science and Engineering specialty. Through the study of three ranging experiments, students have a better understanding of optical communication system technology, the working mechanism of laser transmitting and receiving devices, and the design and implementation of photoelectric engineering circuits. Through the design and experiment of ranging system, students’ comprehensive application ability and design ability have been greatly improved.
