    摘要: A camera includes a set of sensing elements. Each sensing element is arranged at an image plane in an energy field to measure a magnitude and sign of a local gradient of the energy field. Each sensing element includes at least two energy intensity sensors. Each energy sensor measures a local intensity of the energy field. Logarithms of the intensities are subtracted from each other to obtain the magnitude and sign of the gradients. A Poisson equation is solved using the gradients to obtain an output image of the energy field.

    摘要: A method and system deblurs images acquired of a scene by a camera. A light field acquired of a scene is modulated temporally according to a sequence of ons and offs. An optimal coding pattern is selected. The modulated light field is integrated by a sensor of a camera during an exposure time to generate an encoded input image. The encoded input image is decoded according to a pseudo-inverse of a smearing matrix to produce a decoded output image having a reduced blur.

    摘要: An optical system performs agile spectrum imaging. The system includes a first lens for focusing light from a light source. The focused light is dispersed over a spectrum of wavelengths. A second lens focuses the dispersed light onto a mask. The mask selectively attenuates the wavelengths of the spectrum of the light source onto an image plane of the light destination. Depending on the arrangement of the light source and destination, the system can act as a 2. The apparatus of claim 1, in which the light source is a scene and the light destination is sensor, and the apparatus operates as an agile spectrum camera, viewer, spectrum projector, or light source. The arrangement can also be combined to provide a stereo vision system.
