Classification: CPC G | IPC G

Claim 14:
15. A system for controlling illumination of a field-of-regard, the system comprising:
a control circuit comprising respective outputs for use in driving respective optical emitters amongst a plurality of optical emitters, the control circuit configured to generate a first optical transmit signal comprising a first waveform defined by a first code sequence, and to generate a second optical transmit signal comprising a second waveform defined by a second code sequence, the second code sequence separable from the first code sequence using a difference in respective correlation properties of the first and second code sequences;
wherein the outputs are configured to provide the first and second optical transmit signals contemporaneously to illuminate respective regions defining the field-of-regard using at least some of the optical emitters included amongst the plurality of optical emitters, wherein transmitting the respective transmit signals contemporaneously comprises a transmit event;
wherein an angular range of the regions is adjusted between respective transmit events.
