Abstract
A code scanner includes a laser beam generating a flying spot across a read axis of a code. The flying spot generates modulated reflected illumination that is detected by a photodetector assembly. The photodetector assembly includes a lenticular array with a plurality of lens elements and a mask with a plurality of horizontal mask space regions bounded by opaque regions to block a portion of ambient illumination and improve a signal to noise ratio.
