A device including a plurality of epitaxial chips is disclosed. An epitaxial chip can have one or more of a light source and a detector, where the detector can be configured to measure the optical properties of the light emitted by a light source. In some examples, one or more epitaxial chips can have one or more optical properties that differ from other epitaxial chips. The epitaxial chips can be dependently operable. For example, the detector located on one epitaxial chip can be configured for measuring the optical properties of light emitted by a light source located on another epitaxial chip by way of one or more optical signals. The collection of epitaxial chips can also allow detection of a plurality of laser outputs, where two or more epitaxial chips can have different material and/or optical properties.

This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller. The systems and methods disclosed can be capable of accounting for drift originating from the light source, one or more optics, and the detector by sharing one or more components between different measurement light paths. Additionally, the systems can be capable of differentiating between different types of drift and eliminating erroneous measurements due to stray light with the placement of one or more modulators between the light source and the sample or reference. Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Reference switch architectures for noncontact sensing of substances

Methods and systems for measuring one or more properties of a sample are disclosed. The methods and systems can include multiplexing measurements of signals associated with a plurality of wavelengths without adding any signal independent noise and without increasing the total measurement time. One or more levels of encoding, where, in some examples, a level of encoding can be nested within one or more other levels of encoding. Multiplexing can include wavelength, position, and detector state multiplexing. In some examples, SNR can be enhanced by grouping together one or more signals based on one or more properties including, but not limited to, signal intensity, drift properties, optical power detected, wavelength, location within one or more components, material properties of the light sources, and electrical power. In some examples, the system can be configured for optimizing the conditions of each group individually based on the properties of a given group.

Methods and systems for measurement time distribution for referencing schemes are disclosed. The disclosed methods and systems can be capable of dynamically changing the measurement time distribution based on the sample signal, reference signal, noise levels, and SNR. The methods and systems can be configured with a plurality of measurement states, including a sample measurement state, reference measurement state, and dark measurement state. In some examples, the measurement time distribution scheme can be based on the operating wavelength, the measurement location at the sampling interface, and/or targeted SNR. Examples of the disclosure further include systems and methods for measuring the different measurement states concurrently. Moreover, the systems and methods can include a high-frequency detector to eliminate or reduce decorrelated noise fluctuations that can lower the SNR.

This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.

Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.
