MetadataShow full item record
A system to measure the modulation transfer function 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 o conducted with a gyro-stabilized 6328 A laser mounted on board the R. V. ACANIA. The propagation path was approximately lkm over open water from the ACANIA to Point Pinos. Two more o successful trials were conducted with a 6328 A laser and a 10. 6u laser propagating simultaneously from shore to shore across 4km of the southern end of Monterey Bay. Data was processed using fast Fourier transform methods. The MTF of o the atmosphere for 6328 A light was measured.
