1.A SCANNING MIRROR SHORT MILLIMETER WAVE FIELD PATTERN AUTOMATIC MEASURING SYSTEM
3.Tunable CW Ti : Al_2O_3 laser with four-mirror folded cavity compensating the astigmation of the Brewster—angle Ti : Al_2O_3 rod and with complex birefringent filter tuning the wave—length was demonstrated.
5.A theory of compensating atmospheric turbulence by optical phase conjugation is developed basing on the transmission theory of monochromatic scalar wave through atmosphere and the first Born approximation. It is shown, under the conditions of the nonabsorbing atmosphere and a infinite phase conjugate mirror, that atmospheric turbulence can be corrected thoroughly.
