Performance of a time of flight (ToF) laser range finding system using acoustic-based direction of arrival (DoA)

A method comprising:

• determining at least an azimuthal direction to an object based on sound emitted by the object according to programming;
• responsive to detecting the sound at a detecting device, energizing at least one laser apparatus of the detecting device;
• and
• transmitting laser range-finding beams from the laser apparatus according to the determining of at least the azimuthal direction to the object.

A device comprising:

• at least one processor configured to:
• receive at least a first acoustic signal from a source of sound, the first acoustic signal comprising information identifying the source of sound;
• determine at least an azimuthal direction to the source of sound from an origin based at least in part on the first acoustic signal;
• and
• transmit at least a first range-finding beam based on the azimuthal direction determined based at least in part on the first acoustic signal, wherein the information identifying the source of sound comprises a time of emission of the first acoustic signal being according to a schedule.
