System-on-Chip Implementation of a Self-Configuration System for a Programmable Photodetector ASIC

Abstract

In this work a self-configuration system for a photodetector sensor with programmable pixels is presented. The design is part of an optical encoder based on a non-diffractive light beam. The self-configuration is a routine of configurations, readings and successive reconfigurations whose main purpose is finding the center of the non-diffractive beam incident on the sensor, and then configure around it the detection pattern. This algorithm is implemented on a Zynq-7000 SoC and makes it possible to automate the alignment of the beam with the detection pattern, without using micrometric positioning procedures.
