Abstract
A system comprises a waveguide apparatus comprising a plurality of input waveguides, a multimode waveguide, and a guided-wave transition coupling the plurality of input waveguides to the multimode waveguide. The system further comprises at least one light source configured to excite in turn each of a plurality of the input waveguides, or each of a plurality of combinations of the input waveguides, thereby generating a plurality of different light patterns in turn at an output of the waveguide apparatus. The waveguide apparatus is configured to direct each of the plurality of different light patterns to a target region. The system further comprises at least one detector configured to detect light transmitted, reflected or emitted from the target region in response to each of the different light patterns, and to output signals representing the detected light.
