Abstract:

The document is the first quarterly technical report under the contract. Work during the quarter was concentrated on temporal spectra of phase difference fluctuations of atmospherically degraded spherical waves and on averaging times of optical random data. The temporal spectra derivation considered the case of a horizontal wind transverse to the optical path but with the phase measurement points oriented so that their separation vector makes an arbitrary angle with the horizontal. The spectra also included outer scale effects. The averaging time discussion outlined a technique for determining the averaging time of random data while the data is being recorded but in a time much shorter than the total data duration.
