1. A system, comprising:

  • a plurality of optodes configured to be embedded in tissue, wherein each optode is at a respective location, wherein an excitation light causes the optodes to emit emission light, and wherein the optodes are sensitive to at least one analyte such that the emission light emitted by the optodes is indicative of a presence or absence of at least one analyte in the tissue;

    one or more light sources, wherein the one or more light sources are configured to illuminate the plurality of optodes with the excitation light;

    an optical filter array, wherein the optical filter array includes for each optode in the plurality of optodes a corresponding plurality of optical filters;

    a detector array optically coupled to the optical filter array, wherein the detector array includes for each optode in the plurality of optodes a corresponding plurality of detectors configured to detect light received from the optode'"'"'s respective location via the optode'"'"'s corresponding plurality of optical filters; and

    a controller comprising at least one processor, wherein the controller is programmed to carry out operations, the operations comprising;

    operating the one or more light sources to illuminate the plurality of optodes with excitation light;

    operating the detector array to obtain detector information, wherein the detector information includes for each optode a respective optode signal indicative of light that has been emitted from the optode'"'"'s respective location in response to the illumination from the one or more light sources, filtered through the optode'"'"'s corresponding plurality of optical filters, and detected by the optode'"'"'s corresponding plurality of detectors; and

    detecting at least one analyte based on the detector information.
