Optical beam center position on an array of detectors is an important parameter that is essential for estimating the angle-of-arrival of the incoming signal beam. In this paper. we have examined the beam position estimation problem for photon-counting detector arrays. and to this end. https://www.roneverhart.com/BULK-PACK-3-12-Ivory-Dragon-Cloud-Premium-Texture-Fibrous-Paper-Lantern/
