wide mirror 中文意思是什麼
wide mirror
解釋
寬反射鏡-
The optical manufacturing for off - axis aspheric mirrors has become increasingly challenging for two reasons. the mirrors, in addition to being larger, are more aspheric and off - axis in order to meet the requirement of next generation space camera, which is commonly configured as three - mirror - anastigmat ( tma ) to get both wide fov and high resolution, and the required accuracy is more stringent
近年來，人們提出了「離軸三反消像散」 （ tma ）結構來滿足下一代空間相機「詳查」和「寬覆蓋」的技術要求，該結構中要求使用三塊離軸非球面反射鏡，而大口徑、高精度離軸非球面反射鏡的製造技術是研製tma結構空間相機的主要技術瓶頸之一。 -

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。 -
The thesis has done the widespread investigation and study to the domestic and foreign ’ s technologies of analogy low voltage and low power, and analyzes the principles of work, merts and shortcomings of these technologies, based on the absorption of these technologies, it designs a 1. 5v low power rail - to - rail cmos operational amplifier. when designing input stage, in order to enable the input common mode voltage range to achieve rail - to - rail, it does not use the traditional differential input pair, but use the nmos tube and the pmos tube parallel supplementary differential input pair to the structure, and uses the proportional current mirror technology to realize the constant transconductance of input stage. in the middle gain stage design, the current mirror load does not use the traditional standard cascode structure, but uses the low voltage, wide - swing casecode structure which is suitable to work in low voltage. when designing output stage, in order to enhance the efficiency, it uses the push - pull common source stage amplifier as the output stage, the output voltage swing basically reached rail - to - rail. the thesis changes the design of the traditional normal source based on the operational amplifier, uses the differential amplifier with current mirror load to design a normal current source. the normal current source provides the stable bias current and the bias voltage to the operational amplifier, so the stability of operational amplifier is guaranteed. the thesis uses the miller compensate technology with a adjusting zero resistance to compensate the operational amplifier
