摘要:
An imaging optical code reader is adapted for use in producing video displays. A rotating plate carrier is capable of placing several different optical elements into the optical paths of the system including at least one plane parallel plate to change the system focal distance.
摘要:
An imaging engine and signal processing devices and methods are disclosed for reading various kinds of optical codes. The compact structure may include a two dimensional image sensor, apparatus for focusing images at different focal disclosures, an aiming system, a hi-low beam illumination system and related signal processing circuits.
