摘要
Two simple and effective methods of interference-transverse shift technique and longitudinal shift technique-are proposed by using a photorefractive crystal as a real-time recording and reconstruction device. Their principles are analysed through the measurement of refractive index. Some experimental results are also given. These principles and techniques can be used for optical testing and have adequate accuracy. (C) 1998 Elsevier Science Ltd. All rights reserved.
