Optical chopper 역할
WebAug 4, 2024 · The point of "chopping" is to place the information bearing signal from being near dc having low frequency content to be at a convenient so-called carrier frequency … 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.
