An Experiment to Measure the Modulation Transfer Function of the Atmosphere in the Marine Boundary Layer.
Abstract
A system to measure the modulation transfer function (MTF) of the atmosphere over the ocean has been designed, constructed, and tested. The apparatus employs a high resolution scanning telescope with the capability for use in a broad range of visual and infrared wavelengths. Two successful trials were conducted with a gyro-stabilized 6328 A laser mounted on board the R. V. ACANIA. The propagation path was approximately one km over open water from the ACANIA to Point Pinos. Two more successful trials were conducted with a 6328 A laser and a 10.6 micrometer laser propagating simultaneously from shore to shore across 4 km of the southern end of Monterey Bay. Data was processed using fast Fourier transform methods. The MTF of the atmosphere for 6328 A light was measured. (Author)
