Optical chopper motor
WebMar 11, 2013 · The blades of the chopper have a 1:1 mark:space (duty cycle) ratio. We place the chopper between two optical lenses in order to make the spot size of the laser beam as small as possible when it passes through the chopper, which is important to improve the on/off modulation depth of the intensity of the terahertz pulse with a square pulse … WebORIEL OPTICAL CHOPPER Page 7 2 INTRODUCTION The Model 75160NF Optical Chopper is used to introduce a periodic interruption of a light path in an optical experiment resulting in an amplitude modulation, which is useful for many small optical signal detection schemes. The modulation frequency can be controlled from 4 Hz to 10.65 kHz. Full …
