Digital Implementation of FIR Filters for the Minimize of Optical and Optoelectronic Noise of an Optical Scanning System

Abstract

There are different devices capable of discriminating optical and optoelectronic noise, however, the cost of its implementation and maintenance is expensive. This paper examines the possibility of digitally integrating Finite Impulse Response (FIR) filters into the transducer of an OSS systems to obtain better performance in a real operating environment. In this paper we propose the evaluation of the implementation of different FIR filters in different photo-sensors transducers, such as the Light-Dependent Resistor (LDR) and the Light Emitting Diode (LED).
