摘　　要：设计了基于LabVIEW虚拟仪器和机器视觉的普朗克常量和光波波长测量综合实验装置.该装置以发光二极管为测量对象,综合运用了基于机器视觉技术的NI Vision Builder AI,ImageJ以及科学数据绘图软件Origin测得普朗克常量,其大小与普朗克常量的公认值接近.另外,该装置为学生提供了测量普朗克常量新的思路和方法,可作为对传统光电效应法测量普朗克常量实验的补充,有利于学生创新能力的培养和提高.An integrated experimental device for Planck constant and optical wavelength measurements based on virtual instrument LabVIEW and machine vision was designed.The light emitting diode was used as the light source.The Planck constant could be obtained by using several software,such as NI Vision Builder AI based on machine vision technology,ImageJ and Origin.It could be found that the measured value was closed to the recognized Planck constant.The device provided a new method to measure the Planck constant and could be used as supplyment for the teaching of the traditional experiment of measuring Planck constant by photoelectric effect method,which was conducive to the cultivation and improvement of students’innovation ability.
