  • Publication number: 20110176051
    Abstract: In an apparatus and system for focusing optics an objective lens is configured to collect light from a region of an object to be imaged, said region having a feature with a known geometric characteristic, wherein the geometric characteristic is known before the feature is imaged by the optical device. A focusing sensor is configured to observe a shape of the feature and a splitter is configured to split the collected light into a first portion and a second portion, and directing said first portion through a weak cylindrical lens to the focusing sensor. A processor is configured to analyze the observed shape and determine whether the observed shape of the feature has a predetermined relationship to the known geometric characteristic and a mechanism is configured to autofocus the optical device by moving at least one of the objective lens and the object to be imaged in response to the analysis and determination of the processor. In some embodiments, the feature can be a fluorescent bead.

  • Patent number: 7826977
    Abstract: Systems and methods for high-speed image scanning are disclosed herein One aspect of the invention is directed to a method for high speed image scanning. The method for high speed image scanning includes adjusting an object using a positioning element; directing a portion of an image of the object toward a sensor by positioning a first mirror relative to the object, and by positioning a second mirror relative to the object and the first mirror; controlling the positioning element, the position of the first mirror and the position of the second mirror using a processor; and detecting the portion of the image of the object using the sensor positioned relative to the first mirror and the second mirror. In accord with this method, the first mirror directs the portion of the image of the object in a first direction and the second mirror directs the portion of the image of the object in a second direction.

  • Patent number: 5818054
    Abstract: A method and apparatus for non-invasively determining the internal composition of objects are disclosed. The object of interest is probed with low energy, monoenergetic narrow beams of fast neutrons. The object is generally placed on a conveyor belt which is positioned between the accelerator and the detectors. Detectors, positioned at radial angles corresponding to the resonance energy levels of certain preselected elements, measure the neutrons that are not absorbed or scattered by the elements in the object and thus pass straight through the object. The information obtained from the detectors can then be used for subsequent tomographic reconstruction.
