Abstract:
1. A method for illuminating a target, comprising: emitting one or more light beams from a light source, the one or more light beams having a first divergence; receiving the one or more light beams with the first divergence at a lens separated from the light source; changing, at the lens, the first divergence of the one or more light beams to a second divergence, the second divergence being less than the first divergence, the second divergence being greater than zero; transmitting, from the lens, the one or more light beams with the second divergence; receiving the one or more light beams with the second divergence at a collimator coupled to a combiner; collimating the one or more light beams using the collimator; and superimposing the one or more collimated light beams on a target using the combiner.
