Optical tomography sensor and related apparatus and methods

An optical apparatus, comprising:

• a plurality of optical sources;
• a plurality of optical detectors, wherein the plurality of optical sources and plurality of optical detectors are arranged in combination in an array and disposed on a flexible substrate to form a flexible array;
• wherein the flexible array is configured to conform to a subject and wherein the optical apparatus has an outer surface configured to contact the subject such that the plurality of optical sources is configured to direct optical radiation toward the subject and the plurality of optical detectors is configured to detect the optical radiation after passing through the subject;
• wherein at least one optical source of the plurality of optical sources has an emission point disposed within approximately 3 mm of the outer surface of the optical apparatus;
• and
• wherein at least one optical detector of the plurality of optical detectors has a detection point disposed within approximately 3 mm of the outer surface of the optical apparatus.

An optical sensor, comprising:

• a plurality of optical sources, including a first optical source disposed at a first position of the optical sensor and configured to emit a first plurality of wavelengths and 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;
• a plurality of optical detectors, including 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, wherein the plurality of optical sources and the plurality of optical detectors collectively form an array;
• analog receive circuitry configured to receive an analog signal from the first optical detector of the plurality of optical detectors;
• an analog-to-digital converter (ADC) configured to convert the analog signal to a digital signal,
• wherein the plurality of optical sources, plurality of optical detectors, analog receive circuitry, and ADC are at least partially encapsulated in a flexible support structure configured to conform to a subject.
