醫用成像部門的評價及例行試驗第2 - 2部分:穩定性試驗x射線攝影暗匣和換片器-屏-片接觸和屏-匣組件相對靈敏度Llut the dark curre [ lt ot devices are re1ative high, the value is 52 ll a. 27 p a respective1y at 12v bias
探測器的暗電流在12v下分別為52以a 、 2711a 。光靈敏度分別為0Even with spitzer ' s highly sensitive spectrometer, isolating the light coming from a dim planet orbiting in the immediate vicinity of a bright star is a daunting challenge
即便有「斯必擇」高度靈敏的光譜儀，要分離出一個十分靠近明亮恆星的行星暗淡的光也是令人畏懼的挑戰。After measuring dark current, photocurrent and response to x pulse of gaas detector before and after 1. 7 mev electronic radiation, the response tune, fall time of trailing edge, full width of half maximum ( fwhm ), sensitivity, carrier life, mobility are researched and contrasted. the result shows that the response speed of detector, time resolution ratio and nonlinear of back edge of output signal have been improved greatly after electronic radiation. though sensitivity of the detector reduces, its measuring range can be widened
為了使探測器的性能得到進一步的提高，我們對其進行了電子輻照改性，並測量了本徵砷化鎵探測器和經過1 . 7mev電子輻照的探測器的暗電流、光電流及對x射線的脈沖響應，並對其響應時間，后沿下降時間，半高寬（ fwhm ） ，載流子壽命，靈敏度進行對比，研究，結果顯示經電子輻照后的探測器的性能得到了改善，使響應速度，分辯率進一步提高，並消除了探測器輸出信號后沿的非線性，雖靈敏度有所降低，反而使其測量范圍得以拓寬。Product name : color digital camera products tz - 698a product specifications : size : 130x60x55mm products : high quality images with high image quality and sensitivity, the level of resolution of 420 tv lines, even in very dark under the light of high - quality image can be photographed
高品質圖像，具有高品質的圖像和靈敏度，解析度為420水平電視線，即使在非常陰暗的光線下也能拍攝到高品質的圖像。最低照度是0 . 8lux f1 . 2 。Evaluation and routine testing in medical imaging departments - constancy tests - method for radiographic cassettes and film changers and film - screen contact and relative sensitivity of the screen - cassette assembly
醫療成像科評估和常規試驗.第2部分:穩定性試驗.第2節:屏蔽暗盒組件的x射線暗盒換片器膠片屏蔽觸點和相關靈敏度方法But since then, detector sensitivity has improved 1, 000 - fold, and instrument builders expect soon to wring out another factor of 1, 000
即使是當時最佳儀器的靈敏度，與測得假定的暗粒子所需的靈敏度相比，僅及1 / 1000 。分享友人
