Position Measurement Using CCD Based Opto-electronic Gate

Summary: This paper presents principles of optical position measurement methods based on opto-electronic gate. The opto-electronic gate increases the resolution by using a CCD line sensor instead of a simple photo detector. The use of the CCD line sensor increases the range and precision of measurement. Two optical measurement methods will be introduced in this article. These methods were implemented and verified on developed opto-electronic gate. Basic principles of these methods, configuration of measuring set-up and main results will be described in this article. We will also introduce innovative and powerful concept of opto-electronic gate hardware construction
