✦ Synopsis

Two simple and eective methods of interferenceÐtransverse shift technique and longitudinal shift techniqueÐare 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.
