Abstract
Optical sensors, systems, and methods are described, which may be used to provide or analyze information about a subject. The optical sensor may be placed in proximity to the subject and may include optical sources and optical detectors. The optical sources may irradiate the subject with optical signals and the optical detectors can detect signals from the subject. Analysis of the detected signals can yield information about the subject.
Claims20
An optical sensor, comprising:
- a first optical source disposed at a first position of the optical sensor and configured to emit a first plurality of wavelengths;
- a second optical source disposed at a second position of the optical sensor and configured to emit a second plurality of wavelengths different than the first plurality of wavelengths;
- and
- a first optical detector disposed at a third location of the optical sensor and configured to detect the first plurality of wavelengths from the first optical source and the second plurality of wavelengths from the second optical source.
