Lz. Cai et al., WAVE-FRONT SHIFTING PHOTOREFRACTIVE HOLOGRAPHIC INTERFEROMETER AND ITS APPLICATIONS IN OPTICAL-TESTING, Optics and Laser Technology, 30(1), 1998, pp. 1-5
Two simple and effective methods of interference-transverse shift tech
nique and longitudinal shift technique-are proposed by using a photore
fractive crystal as a real-time recording and reconstruction device. T
heir principles are analysed through the measurement of refractive ind
ex. Some experimental results are also given. These principles and tec
hniques can be used for optical testing and have adequate accuracy. (C
