  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. 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

    同時，我們設計的單光子探測器採用跨阻放大器取信號，有別于傳統的用50 。電阻取信號，用電壓放大器進行信號放大的方式，這為單光子探測取信號提供了一種新的思想。
  6. 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。
  7. 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
  8. 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

    在這方面的研究我們國內相對于國外來說還比較落後，還沒有研究出成熟可行的量子密鑰分發系統。
  9. 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。
  10. Low energy photon detector

    低能光子探測器
