Aspects relate to a compact and low-cost gas analyzer that can be used for different types of gas analysis, such as air quality analysis. The gas analyzer can include a light source, a gas cell configured to receive a sample (e.g., a gas under test), a spectral sensor including a spectrometer and a detector, and an artificial intelligence (AI) engine. Light can enter the gas cell and interact with the sample to produce output light that may be measured by the spectral sensor. The resulting spectrum produced by the spectral sensor may be analyzed by the AI engine to produce a result. The gas analyzer further includes a self-calibration component configured to enable calibration of the sample spectrum to compensate for spectral drift of the spectral sensor.

Aspects relate to an optical fluid analyzer including a fluid cell configured to receive a sample fluid. The optical fluid analyzer further includes optical elements configured to seal the fluid cell on opposing sides thereof and to allow input light from a light source to be sent through the fluid cell and output light from the fluid cell to be input to a spectrometer. The optical fluid analyzer further includes a machine learning (ML) engine, such as an artificial intelligence (AI) engine, that is configured to generate a result defining at least one parameter of the fluid based on a spectrum produced by the spectrometer.

Aspects relate to an integrated and compact attenuated total internal reflection (ATR) spectral sensing device. The spectral sensing device includes a substrate, a spectrometer, and a detector. The substrate includes an ATR element, a microfluidic channel, and a channel interface at a boundary between the ATR element and the microfluidic channel formed therein. The ATR element is configured to receive input light and to direct the input light to the channel interface for total internal reflection of the input light at the channel interface. An evanescent wave produced by a sample contained within the microfluidic channel based on the total internal reflection of the input light attenuates the light output from the ATR element and the resulting output light may be analyzed using the spectrometer and the detector.

Aspects of the disclosure relate to a multi-pass gas cell that includes a set of two or more reflectors, an input collimating optical component, and an output focusing optical component. The input and output optical components are integrated with at least one of the two or more reflectors. For example, the input and output optical components may be integrated on opposite ends of a single one of the reflectors or may be integrated on the same end of a single reflector. The input and output optical components may further be integrated with different reflectors. In some examples, the set of reflectors and optical components may be fabricated within the same substrate.

Aspects of the disclosure relate to a self-referenced spectrometer for providing simultaneous measurement of a background or reference spectral density and a sample or other spectral density. The self-referenced spectrometer includes an interferometer optically coupled to receive an input beam and to direct the input beam along a first optical path to produce a first interfering beam and a second optical path to produce a second interfering beam, where each interfering beam is produced prior to an output of the interferometer. The spectrometer further includes a detector optically coupled to simultaneously detect a first interference signal produced from the first interfering beam and a second interference signal produced from the second interfering beam, and a processor configured to process the first interference signal and the second interference signal and to utilize the second interference signal as a reference signal in processing the first interference signal.

An optical radiation source produced from a disordered semiconductor material, such as black silicon, is provided. The optical radiation source includes a semiconductor substrate, a disordered semiconductor structure etched in the semiconductor substrate and a heating element disposed proximal to the disordered semiconductor structure and configured to heat the disordered semiconductor structure to a temperature at which the disordered semiconductor structure emits thermal infrared radiation.

A Micro-Electro-Mechanical System (MEMS) apparatus provides for self-calibration of mirror positioning of a moveable mirror of an interferometer. At least one mirror in the MEMS apparatus includes a non-planar surface. The moveable mirror is coupled to a MEMS actuator having a variable capacitance. The MEMS apparatus includes a capacitive sensing circuit for determining the capacitance of the MEMS actuator at multiple reference positions of the moveable mirror corresponding to a center burst and one or more secondary bursts of an interferogram produced by the interferometer based on the non-planar surface. A calibration module uses the actuator capacitances at the reference positions to compensate for any drift in the capacitive sensing circuit.
