Abstract
An imaging device is presented for use in an imaging system capable of improving the image quality. The imaging device has one or more optical systems defining an effective aperture of the imaging device. The imaging device comprises a lens system having an algebraic representation matrix of a diagonalized form defining a first Condition Number, and a phase encoder utility adapted to effect a second Condition Number of an algebraic representation matrix of the imaging device, smaller than said first Condition Number of the lens system.
Claims15
An optical system comprising:
- a first lens system and a second lens system, the first lens system collecting light from an object and including a first optical axis and a first Numerical Aperture, the second lens system also collecting light from said object and including a second optical axis parallel to and spaced-apart from the first optical axis and a second Numerical Aperture smaller than the first Numerical Aperture,
- a first imaging detection device located on the first optical axis and configured to detect the light collected by the first lens system and to generate corresponding first image data bore-sight to an image plane, and a second imaging detection device located on the second optical axis and configured to detect the light collected by the second lens system and to generate corresponding second image data also bore-sight to said image plane;
- and
- a control system configured and operable to receive the first image data from the first imaging detection device and the second image data from the second imaging detection device, and process the first and second image data to computationally produce reconstructed image data.
An optical system comprising:
- a plurality of lens systems, each lens system configured to capture at least an image corresponding to an object in a common object plane;
- wherein at least two of the plurality of lens systems have different numerical apertures;
- a control system configured and operable to receive and process the captured images from the plurality of lens systems and the control system also configured and operable to process two or more successive images captured using at least one of the plurality of lens systems;
- the processing including duplicating and shifting the images, producing a combined image and outputting a reconstructed image,
- wherein the reconstructed image is an image with improved image quality comprising a reduction in blur of the object in the common object plane.
