Abstract
An optical scanning apparatus includes: an array of optical emitters to provide a plurality of optical beams; a plurality of corresponding microlenses to receive the optical beams; and a variable collimator to receive the plurality of optical beams from the microlenses. The microlenses and variable collimator are arranged to decouple the illumination spot size of the optical beams from the illumination spot separation of the optical beams such that the illumination spot size and the illumination spot separation at a scanning surface are independently controllable.
