WebIn optical applications this precise match is readily built in to the architecture. Many low level optical signals that need the benefits of a lock-in amplifier are DC or very low frequency. In these applications, an optical chopper is used to modulate the signal. An optical chopper is simply a spinning disk that is divided into vanes and windows.

Web네이버 블로그 coffee bean ayer kerohWebAn optical chopper is a device which periodically interrupts a light beam. Three types are available: variable frequency rotating disc choppers, fixed frequency tuning fork choppers, and optical shutters. A rotating disc chopper was famously used in 1849 by Hippolyte Fizeau in the first non-astronomical measurement of the speed of light. coffee bean ayalaWebThe Optical Choppers offered by Hinds Instruments are resonant devices designed to work at one frequency.
