Patent ID: 11949456
Assignee: BALL AEROSPACE & TECHNOLOGIES CORP.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 11:
12. A communication system, comprising:
a laser emitter transmitting a first temporal code of a first wavelength and a first amplitude toward a target;
the laser emitter transmitting a second temporal code of a second wavelength and a second amplitude from the laser emitter toward the target, wherein the first and second temporal codes are generated simultaneously, and a first wavelength filter switch is used to transmit each temporal code individually;
a variable waveplate or other filter receiving light, wherein the received light comprises one of the first temporal code and the second temporal code;
a processor determining, based at least in part on a distance to the target, an expected wavelength;
a second wavelength filter switch filtering the received light based on the expected wavelength; and
the processor decoding the received filtered first and second temporal codes.
