In countless experimental and R&D laboratories, throughout the world, the need for precise, non-contact motion measurement is evident. The objective of this discussion is to examine the need for non-contact measurement and to become familiar with an electro-optical method for obtaining precise, reliable displacement data -- without contact. Theory of operation, key specifications, capabilities and limitations of this technique are discussed. In conclusion, the electro-optical displacement follower offers a practical solution to many measurement problems. Its flexibility and ease of set-up have established it as an extremely useful laboratory tool.
