An experiment to measure the modulation transfer function of the atmosphere in the marine boundary layer
experimenttomeas00alex.pdf (2.107Mb)Abstract
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.
