郎奇(Ronchi)检验是“光学检测”课中讲述的一种基本测量方法,也是基本实验之一。传统的郎奇检验法由于定量测量很费时间,精度也不高,所以学生做这个实验时,一般只要求定性检验,并多以验证光学象差现象为主。随着电子和计算机技术的发展,把同步位相探测技术用于郎奇检验中,既提高了它的精度,又做到快速定量测量,从而为光学测量提供了一种大型的光机电和计算机一体化的实验装置,对培养学生的综合实验能力非常有利。这台装置是古典光学原理、传统的检验方法与现代技术相结合的产物。这套装置已为学生开出了实验,并取得了较好的效果。下面简要地介绍这套装置。
The Ronchi test is one of the basic measurements described in the Optical Inspection lesson and one of the basic experiments. The traditional Langqi test because of quantitative measurement is time-consuming, accuracy is not high, so students do this experiment, generally only require qualitative test, and more to verify the phenomenon of optical aberrations. With the development of electronics and computer technology, the use of synchronous phase detection technology for Lang test, not only improves its accuracy, but also to achieve rapid quantitative measurement, thus providing a large-scale optoelectronic optical and mechanical and computer integration The experimental device is very beneficial to students’ comprehensive experimental ability. This device is a product of classical optics, the combination of traditional inspection methods and modern technology. This device has been experimenting with students and has achieved good results. Here is a brief introduction of this device.
