摘要： A method of mitigating 2.pi.N phase ambiguity in an adaptive optics control system is disclosed wherein the radiation sensed by a detector within a feedback loop is passed through an aperture having a variable diameter. The turn-on of the adaptive optics control system is initiated with the aperture in an open position to transmit radiation from all actuator zones onto the detector resulting in a convergence free of the 2.pi.N phase ambiguity. The diameter of the aperture is then reduced slowly compared to the bandwidth of the control system to converge to a near diffraction limited output beam at the aperture.

摘要： Various aspects of multiple-channel light transmitting systems are disclosed. The system may include a multiple-wave length light source, a demultiplexer; a modulator, and a wavelocker. The wavelocker is configured to drive the light source such that said multiple wavelengths coincide with the ITU grid. The system may also include other elements including a locker or a mode-locking servo, where the servo is configured to adjust the mode locking method frequency to coincide with the spacing of the ITU grid. Further additional elements may include an optical amplifier or an equalizer. The equalizer may include a filter whose transmission function varies with wavelength.
