Multimodal ocular biometric system
First Claim
1. A system for biometric identification, the system comprising:
- a housing;
at least one user window on a first side of the housing, the at least one user window adapted to accommodate two eyes of a user positioned on the first side of the housing at the same time;
at least one opposing window on a second side of the housing, the at least one opposing window aligned with the at least one user window, wherein transmission of images of objects external to the housing occurs between the at least one user window and the at least one opposing window;
at least one illumination source in the housing emitting photons through the at least one user window to be reflected from each of the two eyes; and
at least two image sensors in the housing for capturing respective images according to the photons reflected from a corresponding one of the two eyes, the image captured from the corresponding one of the two eyes having biometric identification data.

Abstract
A multimodal biometric identification system captures and processes images of both the iris and the retina for biometric identification. Another multimodal ocular system captures and processes images of the iris and/or the from both eyes of a subject. Biometrics based on data provided by these systems are more accurate and robust than using biometrics that include data from only the iris or only the retina from a single eye. An exemplary embodiment emits photons to the iris and the retina of both eyes, an iris image sensor that captures an image of the iris when the iris reflects the emitted light, a retina image sensor that captures an image of the retina when the retina reflects the emitted light, and a controller that controls the iris and the retina illumination sources, where the captured image of the iris and the captured image of the retina contain biometric data.
