Patent ID: 7471399

Claim:
A device comprising: an optical cavity component that includes at least one optical cavity that can contain analyte; with analyte absent, the optical cavity providing output light with a first intensity-energy function; with an analyte present in the cavity, the optical cavity providing analyte-affected output light from the cavity, the analyte-affected output light having a second intensity-energy function different than the first intensity-energy function; a photosensing IC component; and a laterally varying transmission component that, in response to the first and second intensity-energy functions, provides first and second laterally varying photon energy distributions, respectively, on the photosensing IC component, the first and second distributions being different; in response to the first and second distributions, the photosensing IC component providing first and second sensing results, respectively; the first and second sensing results each including at least one of position, size, and intensity information about the respective distribution, the first and second sensing results being different.
