Abstract
An spectral sensor system includes an array of optical sensors arranged on an integrated circuit, an interface between the plurality of optical sensors and a first processing device, a plurality of sets of optical filters configured as a layer located atop the plurality of optical sensors, with each set of optical filters including a plurality of optical filters, each optical filter configured to pass light in a different wavelength range. The spectral sensor system includes a memory configured to interface with the first processing device, the memory configured to store calibration data associated with the plurality of sets of optical sensors. The spectral sensor system further includes second processing device includes an artificial neural network configured to correct a spectral response generated by the plurality of optical sensors and an interface between the first processing device and the second processing device is configured to transmit information therebetween.
