摘要:
An apparatus for capturing images of a target object having a barcode. The apparatus includes a reflector, an LED emitting mostly invisible light, and a photodetector. The LED is configured to emit a first portion of the invisible light toward the target object directly and to emit a second portion of the invisible light toward the reflector. The reflector is configured to redirect at least some of the second portion of the invisible light toward the target object. The photodetector is configured to detect returned invisible light from the target object to generate an electrical signal.
