light chopper

基本解釋

A bandgap voltage reference based on chopper technology was used to enhance the output voltage precision of white-light LED driver.
使用斬波技術(shù)，減小了帶隙基準(zhǔn)源中運(yùn)放的失調(diào)電壓所引起的誤差，提高了基準(zhǔn)源的精度。
Using the optical chopper to modulate the detected light to make it related to the reference squarewave signal is a common method of locking phase detection of weak signals.
其中利用光學(xué)斬光器對(duì)被測(cè)光進(jìn)行調(diào)制使其與方波參考信號(hào)相關(guān)是對(duì)微弱光信號(hào)進(jìn)行鎖相檢測(cè)的一種常用方法。
The amplifier input is a voltage proportional to the photocurrent signal produced by a photodiode, which is irradiated by a modulated light beam at the same chopper frequency.
放大器輸入為電壓信號(hào)，與光敏二極管產(chǎn)生的光電流信號(hào)成比例。調(diào)制光柱以斷路器同樣的頻率照射光敏二極管。
