Abstract: A sensor system comprises a plurality of sets optical sensors arranged on an integrated circuit, the plurality of sets optical sensors having a respective top surface. The sensor system further comprising an interface between the plurality of optical sensors and a processing device configured to transmit information there between and an array of optical filters having a respective bottom surface and a respective top surface, where the bottom surface of the optical filter array is located proximal to the top surface of the plurality of sets optical sensors and each optical filter of the optical filter array is configured to pass a target wavelength range of light to a set of optical sensors. The processor is configured to receive an output from each optical sensor in a set of optical sensors and determine a corrected filter response for the set of optical sensors using crosstalk from light transmitted through optical filters adjacent to the set of optical sensors.

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: A method for measuring body parameters includes irradiating a body area during a first time window using a first illumination source of a predetermined range of optical wavelengths and sampling, by a first plurality of spectral sensors, a first received light spectrum for the body area. The method continues by outputting, via one or more interfaces, information representative of the first received light spectrum during the first time window to a processor. The method continues by irradiating the body area during a second time window using a second illumination source of a predetermined range of optical wavelengths and sampling, by a second plurality of spectral sensors, a second received light spectrum for the body area. The method continues by outputting, via the one or more interfaces, information representative of the second received light spectrum during the first time window to the processor.
