    Abstract: A system for typing biological cells includes a tunable Fabry-Perot etalon, and imaging sensor, and a processor. The imaging sensor acquires one or more images of one or more biological cells from light transmitted through the tunable Fabry-Perot etalon. Each image represents signal associated with one or more wavelengths transmitted through the tunable Fabry-Perot etalon. The processor is configured to determine a type of each of the one or more biological cells. Determining the type uses a machine learning algorithm and is based at least in part on one or more of an image segmentation, a patch extraction, a feature extraction, a feature compression, a deep feature extraction, a feature fusion, a feature classification, and a prediction map reconstruction.

    Abstract: A system for packaging an item with an identifier comprises an identifier adder, a labeler, and a packager. The identifier adder adds one or more types of silica-based tags to an item, wherein each type of silica-based tag has a first signature readable using an optical spectroscopic reader. A label is generated based at least in part on reading the one or more types of silica-based tags of the item using the optical spectroscopic reader. The label includes goods info. The packager includes the label on a package, and wherein the packager includes the item in the package.

    Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity transmitted through the tunable Fabry-Perot etalon. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements using multiple source wavelengths and multiple settable gaps.

    Abstract: A system for determining a calibrated spectral measurement includes a tunable Fabry-Perot etalon, a detector, and a processor. The tunable Fabry-Perot etalon has a settable gap. The detector measures light intensity. The processor is configured to determine the calibrated spectral measurement. The calibrated spectral measurement is based at least in part on a measurement set of detected light intensities for a plurality of settable gaps and a reconstruction matrix. The reconstruction matrix is based at least in part on calibration measurements. For a calibration measurement, a settable gap is selected and a set of input monochromatic source wavelengths is used to measure responses at a detector after transmission through the Fabry-Perot etalon. Each input monochromatic source wavelength is also measured using a radiometer to scale detector measurements.

    Abstract: A system for spectral reading includes a plurality of LEDs, an interface, and a processor. The plurality of LEDs are disposed in a physical array. Light from the plurality of LEDs is enabled to be collimated at a Fabry-Perot etalon. The interface is configured to receive a gap calibration table and power characteristics of a plurality of LEDs. The processor is configured to determine an LED switch table. The LED switch table indicates a set of the plurality of LEDs with power above a threshold at a plurality of wavelengths. The processor is further configured to cause measurement of a sample using the gap calibration table and the LED switch table for a set of gap values and determine measurement results.
