ABSTRACT:
A fiber optic scanner system for reading coded patterns is provided having a single optical fiber extending from the reading end of the scanner tip to a remote terminal. The remote terminal includes an optical signal generator for generating and driving light pulses along the single optical fiber to the reading end of the scanner member so as to illuminate a bar code and obtain reflected pulses therefrom which are carried to the remote terminal receiver and decoded.
