Abstract
A detector for a laser scanner has an array of detector elements disposed in at least one row and side-by-side in a plurality of columns, wherein each detector element comprises a lens receptive of laser light on one face thereof along a light path from the target and outputting light at the other face. The detector elements also include a photodetector for generating an electrical signal in response to light received thereon. The photodetector is mounted at a fixed distance from the other face of the lens and facing the other face to receive light passing through the lens and a preamplifier is mounted adjacent the photodetector on a common substrate for receiving the signal generated thereby.
