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)斬光器對被測光進行調(diào)制使其與方波參考信號相關(guān)是對微弱光信號進行鎖相檢測的一種常用方法。
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，與光敏二極管產(chǎn)生的光電流信號成比例。調(diào)制光柱以斷路器同樣的頻率照射光敏二極管。
