Classification: CPC G  H | IPC G  H

Claim 16:
17. An optical device, comprising:
one or more sources;
an optical load to emit light;
an electrical drive circuit connected to the one or more sources and the optical load, wherein the electrical drive circuit comprises:
a charging circuit path for charging one or more inductive elements;
a main circuit path for generating a main electrical pulse,
wherein a main current provided by the main electrical pulse is direct-current-coupled (DC-coupled) to the optical load; and

a discharging circuit path for generating a compensation electrical pulse by discharging the one or more inductive elements,
wherein a compensation current provided by the compensation electrical pulse is alternating-current-coupled (AC-coupled) to the optical load, and
wherein the discharging circuit path includes a first capacitive element in series between the one or more inductive elements and the optical load,
wherein the charging circuit path includes a second capacitive element in parallel with a source of the one or more sources, and

wherein the electrical drive circuit is to:
combine the main electrical pulse and the compensation electrical pulse into a combined electrical pulse, and
provide the combined electrical pulse to the optical load; and

a controller to control the electrical drive circuit to provide the combined electrical pulse to the optical load by:
causing the charging circuit path to charge the one or more inductive elements for a charging time;
causing the main circuit path to generate the main electrical pulse for a first time interval; and
causing the discharging circuit path to generate the compensation electrical pulse for a second time interval,
wherein at least a portion of the second time interval overlaps with the first time interval; and

wherein the optical load is to emit, in response to the combined electrical pulse, an optical pulse.
