High Speed Two Dimensional Bar Code Detection System
A high speed two dimensional (2D) bar-code detection system (BCDS) with two visible-light laser diodes (LDs) driven by a complementary light emission (CLE) method and by a pulse modulation one with bias current (PMBC), has been newly developed to realize highspeed scanning. The CLE method enables a high effective scanning speed, while still retaining the size of the 2D BCDS small. And also, the PMBC method enables a high-frequency drive of LDs, that is. high-speed scanning. This paper experimentarily demonstrates the effectiveness of these CLE and PMBC drive methods.
