| Abstract: | The
Hartmann Shack(H S) wavefront sensor is the most popular type in adaptive optics system
operated with faint object, because of its outstanding advantages in high light efficiency, simple
structure and large capacity of channels. The characters and accuracy of ICCD and CCD type H
S wavefront sensors operated with faint objects is deeply analyzed and compared. The
algorithm for quantitative analysis is derived, and the experimental results are presented as
well. All of these are useful for selection of technical scheme and engineering design of this
kind of wavefront sensor operated with faint object. |
