Abstract: A method and apparatus for scanning a target region. A divergence of a laser beam during scanning of the target region is set. The laser beam is directed to different locations in the target region at a scan angle. The scan angle of the laser beam is set while the laser beam is directed to the different locations. Changing at least one of the divergence or an amount of change in the scan angle during scanning of the target region changes a resolution for the target region.

Abstract: A light assembly may include a reflector having a focal point in space, and a first light source configured to generate a first light at a first wavelength proximate to the focal point during a first illumination mode. The first light reflects off the reflector as a first collimated beam at the first wavelength. One or more second light sources are configured to direct one or more second light beams at one or more different wavelengths towards the focal point during a second illumination mode. The different wavelength(s) differ from the first wavelength. At least a portion of the second light beam(s) reflects off the reflector as one or more second collimated beams at the different wavelength(s).

Abstract: Described in this application for patent is a novel method and apparatus for modifying a searchlight from a visible-light source to an infrared source. This selective filtering is accomplished by means of a partially filtered cover about the light source which may be moved between first and second positions. In a first position, light projected by the light source passes through an unfiltered section of the lamp cover. In a second position, light projected by the light source passes through a filtered section of the lamp cover.

Abstract: A filter for an illumination device may include wedge-shaped lenses arranged about an opening of the illumination device and pivotable between open and closed positions. When pivoted to a closed position, the lenses substantially cover the illumination device opening and block or filter radiation emitted therefrom. When pivoted to an open position, the lenses lie substantially perpendicular to the plane of the illumination device opening, allowing radiation emitted from the illumination device to pass through the opening unfiltered. In one aspect, the filter may include radially inner and outer supports, and each lens element may be pivotally attached to, and pivot about a radially extending pivot axis extending between, the inner and outer supports.
