Abstract
An optical system 200 includes a light source 202, such as a laser diode. A rotatable mirror 208 is positioned to receive a light beam 220 from the light source 202. A collimating lens 218 is positioned to receive a reflected light beam 222 from the rotatable mirror 208. The collimating lens 218 preferably has a focal length that is about equal to the sum of the distance between the light source 202 and the mirror 208 and the mirror 208 and the lens 218.
