Practical Electro-Optic Deflection Measurement System

From OSI Optoelectronics
 

 

This paper describes an electro-optic displacement measurement system which measures both angular and lateral displacements simultaneously. The system consists of a CW laser, lenses, interference filters, beam splitter, and a position-sending photodiode. The use of the described system has been checked and verified by use in an actual system. The system was used to measure flexure of a ship in a variety of different sea states and the results of these measurements are discussed along with the design criteria.
