摘要：

Inversion of measurements of optical path length of rays traversing a strongly refracting, asymmetric-refractiveindex field in a variety of directions is discussed. An initial estimate of the field is made by computing the inverse radon transform of the data. This estimate is then corrected by an iterative process in which computational ray tracing is used to generate optical path lengths that are indirectly compared with the measured values. The method is applicable to interferometric measurements of temperature or density fields and also to related techniques, such as computer-assisted ultrasonic tomography. © 1979, Optical Society of America.
