Systems and methods for wedge-based imaging using flat surfaces
First Claim
1. A method for image processing light data from a wedge imager, said wedge imager comprising:
- a wedge, a first image sensor and a second image sensor, the method comprising;
inputting image data from the first image sensor, said first image sensor capturing image data of a plurality of bands from a first parity of light transmitted by the wedge imager, said wedge imager comprising a first substantially flat surface and a second substantially flat surface;
inputting image data from the second image sensor, said second image sensor capturing image data of a plurality of bands from a second parity of light transmitted by said wedge imager;
mapping each said band from said first parity and said second parity according to an arc segment associated with each said band to form a plurality of undistorted arc segments, each undistorted arc segment associated with one of said bands; and
stitching the image of each of said undistorted arc segments together to form an image input at the first substantially flat surface.

Abstract
A wedge imager and techniques of imaging with a wedge imager are disclosed. In one embodiment, a wedge image comprises: a simple wedge comprising substantially opposing flat faces; a multi-camera and/or optical system to capture light input into the wedge—which is then partitioned into at least two parities of image content. In another embodiment, image processing techniques are disclosed to correct distortion of each parity image content and merge or ‘stitch’ the two parities together to form a single image of the object input surface of the shim wedge. In another embodiment, in order to limit extreme high-FOV (field-of-view) requirements, multiple laterally-neighboring narrow sub-sections may be captured by use of an array of the dual-image sensors and imaging optics, along a single end of the wedge.
