ABSTRACT:
A scanner including first and second light monitor elements and a light redirection system operable in a first mode to focus light reflected from a scanned object and the first light monitor element onto a sensor and operable in a second mode to focus light reflected from the object and the second light monitor element onto the sensor. The light monitor elements are arranged such that the first light monitor element will not interfere with scans in the second mode, which may be a high resolution scan mode, and the second light monitor element will not interfere with scans in the first mode, which may be a normal resolution scan mode.
