Television system for the measurement of atmospheric OTF degradation.
A television system utilizing videotape recorder storage is used to store a large number of images degraded by the atmosphere. By using a large number of samples one can obtain an accurate value for the system-atmosphere MTF. The measured transfer functions are in agreement with Fried's analysis, and the values for the index of refraction structure constant are comparable with those obtained from scintillation measurements.
