Systems and Methods for Selecting Light Emitters for Emitting Light

A method comprising:

• during a first period, charging a plurality of capacitors, wherein each capacitor in the plurality of capacitors corresponds to a respective light emitter in a plurality of light emitters;
• during a second period, discharging one or more capacitors of the plurality of capacitors;
• and
• during a third period, discharging one or more undischarged capacitors of the plurality of capacitors through one or more corresponding light emitters of the plurality of light emitters, thereby causing the one or more corresponding light emitters to emit respective pulses of light.

A non-transitory computer readable medium having instructions stored thereon that when executed by a processor cause performance of a set of functions, wherein the set of functions comprises:

• during a first period, charging a plurality of capacitors, wherein each capacitor in the plurality of capacitors corresponds to a respective light emitter in a plurality of light emitters;
• during a second period, discharging one or more capacitors of the plurality of capacitors;
• and
• during a third period, discharging one or more undischarged capacitors of the plurality of capacitors through one or more corresponding light emitters of the plurality of light emitters, thereby causing the one or more corresponding light emitters to emit respective pulses of light.
