Abstract
An apparatus includes one or more MEMS mirrors, a light source driver and a controller. The light source driver selectively drives one or more light emitting elements of a light source to thereby produce a light beam that is directed towards a same MEMS mirror. The controller controls rotation of the MEMS mirror(s) in a fast-axis direction and a slow-axis direction in order to raster scan an image using the light beam reflected from the MEMS mirror(s). In order to achieve a first line density in a first portion of the image being raster scanned and to achieve a second line density, that is less than the first line density, in a second portion of the image being raster scanned, the controller dynamically adjusts a speed at which one of the MEMS mirror(s) is rotated in the slow-axis direction. Related systems and methods are also disclosed herein.
