论文摘要
考虑到要感应的源可能与未解决的源不同，即扩展，并且它也可以以3D方式部署，足以超越观察望远镜的田地深度。在这些条件下，指出参考的特征对于学生在瞳孔上的不同位置并不不变，并且表明Ingot WFS与激光导向星的金字塔相当。在这种情况下，人们可以想象使用深色WFS方法来改善此类WFS的SNR，或者使用校正后的向上光束，以便更好地利用LGS光子相对于理想的Shack-Hartmann WFS。
The basic outline of a pupil plane WaveFront Sensor is reviewed taking into account that the source to be sensed could be different from an unresolved source, i.e. it is extended, and that it could deploy also in a 3D fashion, enough to exceed the field's depth of the observing telescope. Under these conditions it is pointed out that the features of the reference are not invariant for different position on the pupil and it is shown that the INGOT WFS is the equivalent of the Pyramid for a Laser Guide Star. Under these conditions one can imagine to use a Dark WFS approach to improve the SNR of such a WFS, or to use a corrected upward beam in order to achieve a better use of the LGS photons with respect to an ideal Shack-Hartmann WFS.
