Arrayed Micro-Ring Spectrometer System and Method of Use
First Claim
1. An arrayed spectrometer system comprising:
- an array of microzone plates (MZP) each having a plurality of coaxially-aligned ring gratings configured for diffracting a predetermined wavelength of incident light from a sample onto a target focal point;
a sample plate configured for supporting the sample, and for passing a portion of source light to the sample to generate the incident light; and
an array of photon detectors, wherein each photon detector in the array of photon detectors is operable for detecting a spectral characteristic of the predetermined wavelength.

Abstract
A spectrometer system includes an array of micro-zone plates (MZP) each having coaxially-aligned ring gratings, a sample plate for supporting and illuminating a sample, and an array of photon detectors for measuring a spectral characteristic of the predetermined wavelength. The sample plate emits an evanescent wave in response to incident light, which excites molecules of the sample to thereby cause an emission of secondary photons. A method of detecting the intensity of a selected wavelength of incident light includes directing the incident light onto an array of MZP, diffracting a selected wavelength of the incident light onto a target focal point using the array of MZP, and detecting the intensity of the selected portion using an array of photon detectors. An electro-optic layer positioned adjacent to the array of MZP may be excited via an applied voltage to select the wavelength of the incident light.
