| Zusammenfassung: | The present invention is a dual-light voltage modulation and compensation control circuit for scanner, which includes: a voltage modulation circuit, a first light driver circuit, a second light driver circuit, and a compensation control circuit. The voltage modulation circuit can generate a modulation voltage based on the signal of the amplitude of the modulated pulse. The first light driver circuit can receive the modulation voltage to drive the first light. The second light driver circuit can receive the modulation voltage to drive a second light. And, the compensation control circuit can determine if the modulation voltage is outputted to the first light driver circuit or the second light driver circuit based on a compensation logic signal. |
