Computerized Study of the Linear Optical Incremental Encoder

Abstract:- The paper presents an algorithm that ensures the computerized measurement of some motion parameters (position, displacement, average velocity) using the signals from a linear optical incremental encoder. The working mode of the sensor is with zero initial position or with pre-established target position. This algorithm is adequate for studying the working modes of the sensor with an intelligent system composed by an IBM-PC compatible computer, an interface with a microcontroller from the 80C51 family and a signal conditioning subsystem. Such measurement system is very useful in higher education and research activities. Key-Words:- computerized measurement, linear optical incremental encoder, working mode, displacement, position, velocity.
