Extended depth of field optical systems |
September 1, 2009 |
| An imaging system is characterized at least by an ambiguity function ("AF") and a point spread function ("PSF"). The AF is a function of parameters u and v related to a misfocus parameter .psi.; the PSF is at least a function of .psi.. The system includes (1) an image recording devic |

Wavefront coded imaging systems |
June 30, 2009 |
| A singlet imaging system for imaging an object onto a detector includes a lens configured for producing transverse ray intercept curves which are substantially straight, sloped lines. A wavefront coding element is formed on a surface of the lens and configured such that a modulation |

Non-linear wavefront coding systems and methods |
June 23, 2009 |
| Systems and methods reduce aberrations in a wavefront imaged by an optical system having a non-linear detector. A wavefront of electromagnetic radiation from an object imaged to the non-linear detector is encoded. Data from the non-linear detector is digitally converted to form a dig |

Optimized image processing for wavefront coded imaging systems |
May 27, 2008 |
| An image processing method includes the steps of wavefront coding a wavefront that forms an optical image, converting the optical image to a data stream, and processing the data stream with a filter kernel to reverse effects of wavefront coding and generate a final image. By example, |
