Abstract
Methods, apparatuses and systems for sensing are disclosed herein. An example sensor may include an omnidirectional reflector, a calibration source located inside the omnidirectional reflector and configured to generate one or more calibration beams, a first filter configured to filter one or more first beams including any of a first portion of the incoming beams collected and concentrated by the omnidirectional reflector, and a first detector configured to detect the filtered one or more first beams.
Claims20
A sensor comprising:
- an omnidirectional reflector comprising a reflecting side configured to:
- collect one or more incoming beams from a 360-degree first field of view and a 180-degree or less second field of view;
- and
- concentrate the collected one or more incoming beams using a curvature of the reflecting side;
- a calibration source located inside the omnidirectional reflector and configured to generate one or more calibration beams;
- a first filter configured to filter one or more first beams comprising any of a first portion of the collected and concentrated one or more incoming beams and a first portion of the calibration beams;
- and
- a first detector configured to detect the filtered one or more first beams.

A sensor comprising:
- an omnidirectional reflector comprising a reflecting side configured to:
- collect one or more incoming beams from a 360-degree first field of view and a 180-degree or less second field of view;
- and
- concentrate the collected beams using a curvature of the reflecting side;
- a first dichroic beam splitter located outside the omnidirectional reflector and configured to split the collected and concentrated one or more incoming beams to first and second portions of the collected and concentrated one or more incoming beams;
- a first calibration source located on the first dichroic beam splitter and configured to generate one or more first calibration beams;
- a first filter configured to filter one or more first beams comprising any of the first portion of the collected and concentrated one or more incoming beams and the one or more first calibration beams;
- and
- a first detector configured to detect the filtered one or more first beams.

- a first calibration source located on the first dichroic beam splitter and configured to generate one or more first calibration beams;
- a first filter configured to filter one or more first beams comprising any of the first portion of the collected, concentrated, and reflected one or more incoming beams and the first calibration beams;
- and
- a first detector configured to detect the filtered one or more first beams.
