COMBINED SPECTRAL AND POLARIMETRY IMAGING AND DIAGNOSTICS
First Claim
1. A snapshot imaging spectrometer-polarimeter system for capturing simultaneous spectral and spatially colocalized polarization states from an image of a target scene, the system comprising:
- one or more focal plane array detectors configured to detect light of one or more selected wavelength ranges;
a primary imaging lens and one or more collimating lenses configured along an optical path and to receive an image and focus the image on the one or more focal plane array detectors;
a dispersive optical element configured along the optical path and to disperse the image in two dimensions;
one or more polarizers configured along the optical path;
one or more retarders configured along the optical path; and
an acquisition system configured to collect data from the one or more focal plane array detectors.

Abstract
Combined spectral and polarimetry imaging and diagnostic techniques are disclosed, including an imaging system that simultaneously records spatially co-registered spectral and polarization information from an image of a target scene such as an ocular structure or material or device in an around the eye. Image acquisition and image calibration by such an imaging system or an imaging spectrometer or polarimeter are also disclosed. Methods of data storage and image display relevant to medical practice in general and ophthalmology practice specifically are further disclosed.
