title: Photoelectric fringe strength measurement.
abstract: Experiments in photoelectric measurement of interference fringe strengths by means of a scanning photometer are described. The observed performance of the system is compared with the theoretical prediction for such a configuration. Signal-to-noise ratio variation and turbulance effects are studied. A high precision measurement of source angular diameter with this technique is demonstrated.
