CAMERA USING BEAM SPLITTER WITH MICRO-LENS IMAGE AMPLIFICATION
First Claim
1. An imaging system comprising:
- a taking lens unit adapted to focus light from a scene;
a beam splitter receiving light from the scene with a portion of the received light traveling from the beam splitter to a first imaging surface and a portion of the received light traveling from the beam splitter to a second imaging surface;
a first image capture system for capturing an image based upon the light traveling to the first imaging surface;
a second image capture system for capturing a second image based upon the image formed at the second imaging surface; and
an array of micro-lenses in optical association with the first imaging surface, with each micro-lens in the array concentrating a first fraction of the light from the beam splitter onto concentrated image areas of the first imaging surface;
wherein the first image capture system forms an image based upon the light concentrated onto the concentrated image areas.

Abstract
In one aspect, an imaging system is provided. The imaging system has a taking lens unit adapted to focus light from a scene, and a beam splitter receiving light from the scene with a portion of the received light traveling from the beam splitter to a first imaging surface and a portion of the received light traveling from the beam splitter to a second imaging surface. A first image capture system is provided for capturing an image based upon the light traveling to the first imaging surface, and a second image capture system is provided for capturing a second image based upon the image formed at the second imaging surface. An array of micro-lenses is in optical association with the first imaging surface, with each micro-lens in the array concentrating a first fraction of the light from the beam splitter onto concentrated image areas of the first imaging surface. Wherein the first image capture system forms an image based upon the light concentrated onto the concentrated image areas.
