  3. 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。

  5. It is found that : ( 1 ) for linear slope, redistribution of incoming energy flux in modenumber space depends on both the modenumber of incident waves and the ratio of the slope of incident wave ray to slope of topography ; both the transmitted and reflected energy flux ( only for supercritical linear slope ) focus near one or two modenumbers ; for supercritical linear slope, the energy flux scattering to higher modenumbers becomes larger and the energy flux to lower modenumbers becomes smaller as the slope of incident wave ray comes near to slope of topography ; ( 2 ) for convex slope, energy flux is redistributed in wide - range modenumbers and also show peaks on lower - modenubers and higher - modenumbers ; ( 3 ) for concave slope, energy flux is also redistributed in wide - range modenumbers, but does not show peaks on higher - modenumbers as supercritical linear slope and convex slope do ; ( 4 ) the total energy flux scattering to higher modenumbers is approximately equal to the total energy flux to lower modenumbers for internal waves propagating over both convex slope and concave slope, which means the concave slope is the same efficient to convex slope in scattering energy flux to higher modenumbers ; ( 5 ) for convex slope, the wave ray reflected from near - critical topography can extend to deep ocean and shallow shelf, while for concave slope, the wave ray reflected from near - critical topography can only extend to limited distance, then meet the topography and be reflected again ; generally the shear of the internal waves reflected twice from concave slope is not enhanced while the enhanced shear does also appear before second reflection takes place, the enhanced shear can bring about intense mixing, so internal waves reflected from concave slope can also produce marked mixing near critical slope

    3 、內波在凹地形上傳播時，能通量在模態上的分佈范圍也比較寬，但與凸地形和超臨界線性斜坡地形相比，能通量在高模態上的分佈沒有明顯的峰值。 4 、從總的能通量來講，內波在凸地形和凹地形上傳播時，向高模態散射的能通量與向低模態散射的能通若十地形下內波傳播及內潮生成問題的理論解量近似相等，這意味著二者在向高模態散射能通量方面具有同等效率。 5 、凸地形上臨界點附近的反射，反射波的波射線能夠延伸到深海和陸架，凹地形上臨界點附近的反射，反射波的波射線很快遇到地形發生二次反射，一般來講二次反射后回到深海的波動其速度剪切並不很強，但是在進行二次反射之前的區域，速度剪切仍然很強，因而內波在凹地形上的反射依然能夠在地形附近區域，產生強的速度剪切區，誘發混合。
