Claim 9:
10. A method for performing optical detection using encoded transmit sequences, the method comprising:
receiving an optical signal corresponding to light scattered or reflected from an object in a field-of-view of an optical receiver, the scattered or reflected light elicited by contemporaneously transmitted first and second optical transmit signals, the first optical transmit signal comprising a first waveform defined by a first code sequence and the second optical transmit signal comprising a second waveform defined by a second code sequence, wherein the first optical transmit signal and the second optical transmit signal illuminate respective regions defining a field-of-regard, wherein transmitting the respective transmit signals contemporaneously comprises a transmit event;
determining a first sample index where a correlation between the received optical signal and a representation of the first code sequence is enhanced;
estimating a depth to the object corresponding to the determined first sample index; and
adjusting an angular range of the regions between respective transmit events.
