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。 -
