... If the guiding algorithm does not account for this effect, it will tend to see larger centroid shifts than are really occurring. This in turn can cause the algorithm to “overguide,” telling the telescope to move larger amounts than are appropriate. The entire guiding system includes the latency in g ...

Imaging Properties of Laser-Produced Parabolic Profile Microlenses
... The PSF can be considered as the representation of illumination intensity of point object. If aberrations of an optical system are small then the illumination intensity of point object of real optical system is close to one of ideal optical system. Two groups of microlenses can be seen by analysing ...
