  2. 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，主要對量子通信用單光子探測器的核心器件? ? ingaas雪崩光電二極體（ ingaas - apd ）的暗電流特性、光電流、溫度特性、雪崩特性等進行了研究，同時把飛通公司、 oki公司、 perkinelmer公司的apd進行了比較，分別得出了它們的特性參數，為研製實用的紅外單光子探測器提供了重要的依據。
  3. The pin silicon photodiode made by alice - china group, which has a large area and high performances, is an important part of the photon spectrometer ( pros ) pbwo4 detector read - out system on the alice experiment. the pin diode has a sensitive area of 16x17 mm2. its leakage current is lower than 5na at room temperature

    本工作研製的pin硅光電二極體的靈敏區面積為16x17mm2 ，常溫漏電流小於5na ，紫光區量子效率約為83 % ，結電容為110 - 120pf ，以及由pin光電二極體與電荷靈敏前置放大器組成的讀出系統的噪聲水平在- 25下小於527個等效噪聲電荷，並經過了長期性能穩定性的考驗
  4. In euv and soft x - ray band, the most often used detector is ion chamber with rare gas, from whose collective electrode we can directly calculate intensity of photon flux

    在極紫外和軟x射線波段常用的探測器是稀有氣體電離室，可以通過電離室收集極的收集電流直接計算出光子流強度。
  5. The object of single photon emission computed tomography ( spect ) is to reconstruct an unknown radioactivity distribution inside the body from projection data consisting of the number of photon collected on a collimated gamma camera. these projections are not simple line integrals but have point - spreads due to the imperfect collimator of the detector and attenuation due to the compton scattering. so

    這種投影數據與透射ct中的數據不同，由於存在著光子的點擴散（由準直器引起）和衰減（由散射引起） ，已經不能用簡單的線積分來描述這個問題，因此相對于透射ct而言，這個領域將面臨很多困難。
  6. Radiation protection instrumentation - measurement of discrete radionuclides in the environment - in situ photon spectrometry system using a germanium detector

    輻射防護儀器.測量環境中的放射性核素.使用鍺探測器的現場光子光譜測定系統
  7. 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

    本系統的主要原理是:把入射光分為兩束，讓其中一束光通過一個可調光纖延遲線，再把這兩束具有相同幅度並延時重合的光合路後送進雙光子探測器，該探測器同時吸收兩個光子發生雙光子效應從而產生電流信號，且其大小與雙光子自相關信號的強度成正比。
