Abstract:
1. A laser imaging device comprising: a laser unit configured to form a scan line from a video driver signal; and a scan line controller comprising: a pulse width modulator system to receive a pulse code, the pulse width modulator system including a first pulse width modulator to receive a first dot clock having a first frequency and a second pulse width modulator to receive a second dot clock having the first frequency, and to provide the video driver signal to the laser unit; and a space insertion/deletion unit configured to adjust a scan line length by inserting or deleting one or more delays into the first and the second dot clocks, and wherein the pulse width modulator system further comprises a multiplexer configured to receive a selector signal instructing the multiplexer to select between a first video signal and a second video signal provided by the first and the second pulse width modulators, respectively, and with each representative of the pulse code, to thereby provide the video driver signal.
