本文主要圍繞電路故障檢測儀的系統硬體電路和熱圖像質量改善方法進行闡述，主要的創新點和研究內容如下:本文主要的創新點是:提出了改善熱圖像質量的幾種方法，如激勵時間控制、增溫法、降噪法和提高發射率法等。Point diffraction interferometer - a physical idea, is invented by smartt and strong in 1972, advanced by smartt and steel, and used to test astronomical telescope, it has simple structure and has not special demand to source. recently. with the development of fiber ' s manufacture and coupling technology. the simple modern fiber ' s center is smaller than before, this make it possible to progress fiber point diffraction interferometer ( pdi ), in addition to test convergent wavefront, it can test the reflective concave. the excellence of pdi is that it does not need standard mirror. in intereference testing, the standard mirror is the main reason which limit the improvement of precision, pdi can avoid difficulty to provide the wide future for high precision testing. pdi, which produce the standard sphere wavefront, is an instrument which realize the phase shifting with piezoelectric transducer ( pzt ), and collect the interferogram with ccd, in this paper, a adjusting methord is described, then data processing is obtained
點衍射干涉儀這一物理思想，早在1972年smartt和strong就已發明，由smartt和steel做了進一步發展，並成功的用於檢測天文望遠鏡，它結構簡單，對光源沒有特殊要求，近年來，由於光纖製造工藝以及耦合技術的發展，單模光纖纖芯不斷縮小，為光纖點衍射干涉儀得以發展提供了前提條件，該干涉儀由激光照明，除了檢測會聚波前外，還可以用來檢測反射凹球面，進而應用到單個面形的檢測；另外，光纖點衍射干涉儀最大的優點是不需要標準鏡，在干涉檢測中，標準鏡是檢測精度受限的很大原因，光纖點衍射干涉儀能繞開這一難度，為進行高精度的光學檢測提供了廣闊的前景。In addition, conventional surface analytical tools, i. e., leed and aes, are also equipped to provide surface information of long - range order and elemental identity
傳統的表面分析設備如低能電子繞射儀（ leed ）及歐傑電子能譜儀（ aes ） ，則用來決定晶體表面的長程結構和元素成份。Galileo was further hobbled by an erratic tape recorder. after the craft began orbiting jupiter in 1995, repeated zappings from the planet ' s intense radiation belts damaged other instruments
伽利略號又被一個漂浮在太空的磁帶錄音機所拖累。在飛船1995年後圍繞木星軌道運動時，從行星的強輻射帶發射的循壞的跳過節目的輻射損壞了其他一些儀器。It shows excellent results to reveal the efficiency of the method, also prove the superior science research value of pgpr and give direction for consummating the apparatus next step
