A method and apparatus for estimating the presence of RF interference in a wireless data channel is described. The method and apparatus comprises a set of identical tracking/register (T/R) filter blocks, each T/R filter block associated and corresponding to an RF channel of interest. Each T/R filter block includes a pair of tracking/register (T/R) filters. Power/magnitude estimates from an RSSI calculation are input to the T/R filter blocks. One T/R filter is used to estimate the noise floor (in the absence of interference). The T/R filter latches and filters the lowest input values received from a power/magnitude circuit. The other T/R filter estimates the level of an interferer, if present, by latching and filtering the largest valued outputs of the power/magnitude circuit.

A method and apparatus for reducing speckle in a laser illumination system uses a despeckle device including an optical retarder providing an odd integer multiple of substantially half-wave retardation for light emitted from a coherent laser in the laser illumination system. The near half-wave optical retarder has a substantially constant retardance and a spatially varied slow axis. The spatially varied slow axis imposes a phase mask on the beam of light, which provides sub-resolution optical phase modulation to a resolution spot on the detector. The near half-wave optical retarder is actuated mechanically or electrically to vary the sub-resolution optical phase modulation within an integration time of the detector.
