Hx. Yuan et al., Analysis of effects of light intensity distribution in the phase method todetermine the position of a light spot incident on a position-sensitive detector (PSD), MICROW OPT, 24(1), 2000, pp. 40-45
In this paper the effects of light intensity spatial distribution on the de
termination of rile position of a light spot incident oil a PSD with the ph
ase method are analyzed based on the linear system theory. And two general
cases symmetry distribution and asymmetry distribution, are presented. At t
he same time, we also provide several typical examples of the above eases.
As a conclusion, the spatially symmetry-distributed light source is recomme
