摘要
In the method described, matched pairs of photoresistors are used for the measurement of fringe shifts. Its performance has been checked for sensitivity to light intensity and temperature fluctuations: under reasonable conditions, fringe shifts can be measured to an accuracy of 10-4 fringe. © 1969 Optical Society of America.
