Image correction across multiple spectral regimes
First Claim
1. A method of image correction, comprising:
- collecting a first set of image data in a first wavelength regime, along with phase diversity data;
collecting a second set of image data in a second wavelength regime, without phase diversity data;
processing the first set of image data to determine an image correction factor for correcting the second set of image data; and
correcting the second set of image data by applying the image correction factor to the second set of image data to obtain a corrected set of image data.

Abstract
Systems, including apparatus and methods, for obtaining and/or correcting images, particularly from atmospheric and/or other distortions. These corrections may involve, among others, determining corrective information in a first (e.g., visible) wavelength regime, and then applying the corrective information in a second (e.g., longer) wavelength regime, such as infrared (IR) or millimeter-wave (MMW) wavelengths, in real time or with post-processing. For example, these corrections may include scaling a phase diversity correction from one wavelength to another. These systems may be useful in any suitable imaging context, including navigation, targeting, search and rescue, law enforcement, and/or surveillance, among others.
