Paper Abstract

The purpose of this paper is to describe a new precision displacement sensor--Compact Precision Holographic Optical Probe--with the use of holographic optical element (HOE) technology. It is a novel non-contact method for the measurement and inspection of displacement and surface quality control. The IR HOEs are made by using a computer generated hologram method. A mathematical model has been developed to analyze the performance of the probe. The initial experimental results are obtained. The probe is both compact and inexpensive.
