Patent ID: 7936463

Claim:
A device comprising: a photosensing component with one or more photosensitive surfaces; and an optical cavity structure including: an inhomogeneous transmissive optical cavity with a light-transmissive region between first and second inward reflection surfaces; and an analyte region that can contain analyte within the light-transmissive region, presence of the analyte in the analyte region affecting the optical cavity's output light; the photosensing component being positioned to receive the output light and, in response, the photosensing component providing sensing results that include information about the analyte's optical characteristics, and wherein the photosensing component is further positioned so that received analyte-affected output light has laterally varying wavelength dependent photon energy distribution on the photosensitive surfaces; the photosensing component providing the sensing results indicating the laterally varying wavelength dependent photon energy distribution.
