ABSTRACT:
A multi-bounce, folded path scanning system, including a first and second pair of stationary tracks, the second pair of tracks being angled with respect to the first pair of tracks, and a movable carriage slidably mounted on the first pair of stationary tracks. The system further includes a first mirror fixedly mounted on the movable carriage, a second mirror slidably mounted on the second pair of stationary tracks and opposing the first mirror and forming an acute angle therewith, the mirrors being separated by a predetermined distance, whereby one end of the mirrors is more open than the other end of the mirrors, an input light ray entering at the more open end of the mirrors and incident upon the first mirror at a predetermined angle, wherein the ray is reflected off each mirror a predetermined multiplicity of times and exits the mirrors at the more open end, and means for translating the first and second mirrors, wherein the predetermined distance between the mirrors increases as the mirrors are translated while the correct angular relationship between the mirrors is maintained.
