Classification: CPC G | IPC G

Claim 0:
1. An optical transmitting system for distance measuring, comprising:
a modulation signal generator configured to generate a modulation signal;
a light source configured to generate an optical waveform with amplitude modulation corresponding with the modulation signal; and
a resonant illumination driver coupled to the modulation signal generator and the light source, the resonant illumination driver configured to drive the light source, the resonant illumination driver including:
a first inductor having a first terminal and a second terminal wherein the first inductor is configured to receive a drive current;
a second inductor having a first terminal and a second terminal wherein the first terminal of the first inductor is directly coupled to the first terminal of the second inductor;
a capacitor having a first terminal and a second terminal wherein the first terminal of the capacitor is directly coupled to the second terminal of the first inductor; and
a transistor having a control terminal, a first current terminal and a second current terminal wherein the control terminal is directly coupled to the second terminal of the capacitor wherein the second terminal of the second inductor and the second current terminal of the transistor are coupled to ground.
