    Abstract: A light detection device includes: a first support part disposed on a mounting surface of the wiring board; a Fabry-Perot interference filter disposed in a first support region of the first support part; and a temperature detector, wherein the temperature detector is disposed on the mounting surface such that at least a part of the temperature detector overlaps a part of the Fabry-Perot interference filter when seen in a first direction perpendicular to the mounting surface and such that at least a part of the temperature detector overlaps a part of the first support part when seen in a second direction in which the first support part and the light detector are aligned with each other, and wherein a first distance between the temperature detector and the first support part in the second direction is smaller than a first width of the first support region in the second direction.

    Abstract: A spectral apparatus includes: an interference filter that includes a pair of reflection films and outputs light having a spectral wavelength corresponding to a gap size between the pair of reflection films; a gap sensor that detects the gap size; and one or more processors configured to detect an error based on a difference between the spectral wavelength corresponding to the gap size detected by the gap sensor and a target wavelength of light to be output from the interference filter. The one or more processors detect an error when an integration value obtained by integrating, on a time axis, an absolute value of the difference exceeds a threshold value.

    Abstract: A sensor system has a plurality of optical sensors configured in an array on an integrated circuit and a lens system located proximal to a top surface of the array, where the intersection of the optical axis of the lens system with the plurality of optical sensors defines a reference point for light passing through the lens system. The sensor system includes a plurality of sets of optical filters overlaying the array between the lens system and the array, with each set of optical filters being associated with a set of optical sensors of the plurality of optical sensors and a set of optical filters of the plurality of sets of optical filters includes a plurality of optical filters where each set of optical filters has a center wavelength for light transmitted through the set of optical filters. In the sensor system each optical filter of the plurality of optical filters is configured to pass light in a different wavelength range, with at least some sets of optical filters configured to provide a center wavelength that is higher than a center wavelength of a set of optical filters at the reference point. An interface is provided for receiving output signal representative of received light from the optical sensors and to output signal from the plurality of optical sensors, with the output signal being representative of received light from the plurality of optical sensors and a spectral response is determined for each set of optical sensors associated with a set of optical filters.

    Abstract: Spectrometers include an optical assembly with optical elements arranged to receive light from a light source and direct the light along a light path to a multi-element detector, dispersing light of different wavelengths to different spatial locations on the multi-element detector. The optical assembly includes: (i) a collimator arranged in the light path to receive the light from the light source, the collimator including a mirror having a freeform surface; (2) a dispersive sub-assembly including an echelle grating, the dispersive sub-assembly being arranged in the light path to receive light from the collimator; and (3) a Schmidt telescope arranged in the light path to receive light from the dispersive sub-assembly and focus the light to a field, the multi-element detector being arranged at the field.

    Abstract: A drug scanning and identification system including a spectrometer, a drug holder, a mobile device and a drug identification model is provided. The spectrometer includes a light source, a diffraction grating, a light-absorption element, a wavelength selector, and a single-point photodetector. The drug holder includes a transparent area and a light-absorption area. The drug is disposed on the transparent area. The light-absorption area surrounds the transparent area. The mobile device is adapted to send a control command to trigger the spectrometer scanning the drug so as to obtain spectrum data of the drug. The spectrometer is adapted to transmit the spectrum data of the drug to the drug identification model. The drug identification model is adapted to identify the spectrum data of the drug such that the drug identification model generates an identification result. The identification result is displayed by the mobile device.
