Patent ID: 7746450

Claim:
An imaging system, comprising: a transmitting module configured to transmit a transmitted optical signal containing a transmitted pulse, the transmitted pulse being modulated with a selected pseudo-noise (PN) code, the transmitted optical signal arranged to illuminate a target space containing a first object, wherein the transmitting module is configured to include identification information in addition to the selected PN code, the identification information is contained in the transmitted optical signal, the identification information comprises a plurality of bits that represent a source identification of the selected PN code, and the source identification comprises a vehicle identification; a receiving module configured to receive a reflected optical signal reflected from the first object and to derive a first received pulse from the reflected optical signal; an optical array configured to detect a detected signal from the reflected optical signal across a plurality of pixels of the optical array, the detected signal spanning the target space, a first pixel being contained in the plurality of pixels; and a processing module configured to process data for the plurality of pixels by: determining first pulse characteristics of the first received pulse; obtaining first positional information for the first object from the first pulse characteristics; when the selected PN code is detected from the first pixel, providing first image information and the first positional information for the first object; and discarding second pixel data for a second pixel when a PN code associated with the second pixel is different from the selected PN code, wherein the PN code associated with the second pixel is generated by a source that is different from the transmitting module that is associated with the selected PN code.
