摘要: A processing system includes a transmitter module, receiver and determination module. The module drives first optical with coded signal based on code, second code. code the are non-orthogonal, transmit at overlapping times. receives resulting that effects corresponding to signal. determines measurement between receiver, positional information for an input object measurement.
