Abstract
An optical system and method for data reading including a light source which generates an optical beam directed toward an object, a pivoting scan mirror which directs the optical beam over a scanning range on the object to be read, a stationary collection mirror for collecting light from the object, a fold mirror positioned behind the scan mirror for reflecting light collected by the collection mirror through an aperture in the collection to a photodetector.
