Abstract
Systems and methods that incorporate a variable liquid lens are disclosed. In at least some embodiments, a light projecting system includes a light source, and a light processing assembly configured to receive a light beam from the light source and to project an output field. The light processing assembly includes at least one liquid lens configured to controllably process the light beam such that the output field is variable between a relatively-broader illuminating field and a relatively-narrower targeting field. In some embodiments, a controller may controllably adjust the at least one liquid lens to alternately provide the illuminating field and the targeting field, and may controllably adjust at least one dwell time to adjust a brightness of at least one of the illuminating and targeting fields, respectively.
