Optical attenuation, widely applied in many fields, can be adopted to acquire single - photon sequence that is foundational in quantum key distribution. we obtain single - photon sequence by precisely controlled optical power distribution along outlets of manifold consist of beam splitter instead of the attenuation by time sequence due to loss
用線性分束耦合器形成多個輸出口,將光強的時序衰減變為光強沿輸出口的空間分佈,研製出了量子保密通信用的精密控制的強衰減器,實現了對光子數的精密控制。Avm is essentially a precision array film attenuator, which has a big diameter, high power load, continuous adjustment. the gain of each beam of the main amplifiers is controlled independently by the adjusting the angle of each cell of avm
Avm實質上是大口徑、高功率負載、透過率連續可調的組合式精密薄膜衰減器,通過調節avm各單元偏轉角度大小來獨立控制住放大器各路的增益。It attenuates the output of the preamp in the same manner as you would experience with a “ passive preamp ” except that it has a precision 256 position 4 pole attenuator for both balanced channels matched to. 1 %
正如你以前見過的「被動前級放大器」那樣,它能夠衰減前級放大器的輸出,並且它具有一個精密的256位4通道衰減器,可以令兩個平衡通道匹配誤差僅為0 . 1 % 。The accurately controlled signal source generates sinusoidal elastic wave accurately controlled in frequency and stable in phase to " illustrate " underground media. time signal stacker receive signal by stacking and doing fft to measure the transfer function of media. " sompi " cepstrum method retrieve group velocity travel times and decayed factors of wave element from observational data of transfer function in a limited frequency window
精密可控震源用於產生頻率精確相位穩定的正弦彈性波以照射地層內部,信號疊加器通過對接收信號進行疊加和進行傅立葉變換的方式實現對介質傳遞函數的精密測量, 「存否」倒譜方法能夠根據一段窄帶頻域傳遞函數數據獲得時域上各個波成分的群速度傳播時間和介質衰減因子。分享友人
