摘要: A method and apparatus for providing current pulses to the illumination source in an imaging scanner. The includes: (1) sensing a supplied from port obtain current-monitoring signal; (2) controlling charge provided storage capacitor based on (3) measuring parameter related voltage across capacitor; (4) generating driving by driver circuit, if is above predetermined threshold value, provide
