ABSTRACT:
The present invention provides scanning beam devices that have one or more detectors positioned within a housing of the device. The detector(s) may be disposed anywhere within the housing to receive light reflected from the target area. In one embodiment, an optical assembly of the device transmits a first portion of the reflected light to a scanning element, and a second portion of the reflected light to the detectors. In another embodiment, the optical assembly is configured to transmit substantially all of the reflected light to the scanning element. In such embodiments, the scanning element will be adapted to allow the light to exit the scanning element and impinge on the detector(s) within the housing.
