Claim 7:
8. A method, comprising:
emitting a nonsinusoidal light signal from a light source during a first time interval;
receiving, at an imager array, in response to the nonsinusoidal light signal, incoming nonsinusoidal light signals including a first reflected nonsinusoidal light signal along a first path and a second reflected nonsinusoidal light signal along a second path;
performing time of flight measurements on the first reflected nonsinusoidal light signal and the second reflected nonsinusoidal light signal to generate a first set of measurements;
receiving the first set of measurements at a processor;
determining, at the processor, a first estimated distance to an object based on the first set of measurements; and
determining a corrected distance to the object based on the first set of measurements using a look-up table.
