Examples with a Single Positive Parameter

摘要: Several interesting problems relating to wave propagation in turbulence are solved this chapter. The Zernike tilt jitter is calculated for finite outer scale with both von Karman and Greenwood models effects. It shown that significantly affects even if the diameter much smaller than scale. inner limits maximum can be measured on an aperture. Tilt annulus, it does not differ from of a filled aperture unless most obscured. effect diffraction calculated. variance goes half its near-field value far field. amount difference between two displaced sources power spectral density found. An asymptotic series describes behavior at high frequencies. I show size apertures reduce scintillation. Characteristic sizes source which reduction significant Inner found scintillation typical inner-scale sizes. Scintillation beam corrected by use beacon sky phase focus found, correlation function problem correcting artificial beacons addressed, variances point, distributed, offset
