Paper Abstract

Chopper is widely used in optical system to produce a series of optical pulses which has particular shape and frequency. This paper presents a way to make a simple chopper based on Labview. Labview and NI DAQ are widely available in universities. So with this method chopper system can be easily constructed for temporary use. NI DAQ uses counter tools to detect the frequency of modulated laser and produce several feedback signal to drive the location and rotate speed of modulation plate, which leads to the change of modulation frequency and duty. This paper can provide a reference for experiment work in optics and other natural science.
