    Abstract: A method comprises applying a first delay to a first signal that is ahead of a second signal in a series of signals and determining a first number of delay units that provides the first delay to change an order between the delayed first signal and the second signal that has a phase difference with the first signal. The method further comprises determining a similar number for any other pair of signals in the series of signals that have the phase difference. The method further comprises determining a maximum and a minimum from the obtained numbers and determining linearity of the seriels of signals based on a difference between the maximum and the minimum.

    Abstract: A laser projection system is disclosed having reduced apparent speckle. The system includes a laser emitting a first beam on an optical element. The optical element emits a second beam incident on a scanner that scans the beam onto a projection screen. The optical element may be an exit pupil expander, delay plate, or have a locally electrically modulated index of refraction. In other embodiments, the laser has a tunable wavelength distribution that is changed for each frame displayed by the projection system to reduce apparent speckle. In still other embodiments, the angular content of a beam incident on a scanner is modulated to produce a time varying speckle pattern.
