photon detector meaning in English
光子检波器
光子检测器
光子探测器
Examples
- Low energy photon detector
低能光子探测器 - So the applied single photon detector is concerned by the scientist . in our country research in this field is relatively backward , and no ripple device is realized in this field
在这方面的研究我们国内相对于国外来说还比较落后，还没有研究出成熟可行的量子密钥分发系统。 - We also designed the single photon detector using the transimpedance amplifier , which is different from the conventional method , and provided a new idea to infrared detection
同时，我们设计的单光子探测器采用跨阻放大器取信号，有别于传统的用50 。电阻取信号，用电压放大器进行信号放大的方式，这为单光子探测取信号提供了一种新的思想。 - In this thesis we have analyzed some kinds of single photon detector and their advantage and disadvantage firstly . then , the key apparatus ( ingaas - apd ) and its characteristics have been studied . we have tested the apds of perkinelmer , oki and photon company , and got some useful parameters
其次，主要对量子通信用单光子探测器的核心器件? ? ingaas雪崩光电二极管( ingaas - apd )的暗电流特性、光电流、温度特性、雪崩特性等进行了研究，同时把飞通公司、 oki公司、 perkinelmer公司的apd进行了比较，分别得出了它们的特性参数，为研制实用的红外单光子探测器提供了重要的依据。 - The fundamental principle of this system is as follows . divide the incident beam into two beams , one of which passing through variable optical delay ( vod ) , then combination of the two beams with the same amplitude and delay - superposition is sent to bi - photon detector and transformed into current signals , whose intensity is proportional to the intensity of bi - photon autocorrelation signals
本系统的主要原理是:把入射光分为两束,让其中一束光通过一个可调光纤延迟线,再把这两束具有相同幅度并延时重合的光合路后送进双光子探测器,该探测器同时吸收两个光子发生双光子效应从而产生电流信号,且其大小与双光子自相关信号的强度成正比。
