摘要： Systems and methods are described for rapid acquisition of fused off-axis illuminated direct-to-digital holography. A method of recording a plurality of off-axis object illuminated spatially heterodyne holograms, each of the off-axis object illuminated spatially heterodyne holograms including spatially heterodyne fringes for Fourier analysis, includes digitally recording, with a first illumination source (120) of an interferometer, a first off-axis object illuminated spatially heterodyne hologram including spatially heterodyne fringes for Fourier analysis; and digitally recording, with a second illumination source (120) of the interferometer, a second off-axis object illuminated spatially heterodyne hologram including spatially heterodyne fringes for Fourier analysis.

摘要： Systems and methods for direct-to-digital holography are described. An apparatus includes a laser; a beamsplitter optically coupled to the laser; a reference beam mirror optically coupled to the beamsplitter; an object optically coupled to the beamsplitter, a focusing lens optically coupled to both the reference beam mirror and the object; and a digital recorder optically coupled to the focusing lens. A reference beam is incident upon the reference beam mirror at a non-normal angle, and the reference beam and an object beam are focused by the focusing lens at a focal plane of the digital recorder to form an image. The systems and methods provide advantages in that computer assisted holographic measurements can be made.

A method of recording an off-axis hologram includes: splitting a laser beam into an object beam (1620) and a reference beam (1685); reflecting the reference beam from a reference beam mirror (1675); reflecting the object beam from an illumination beamsplitter (1630); passing the object beam through an objective lens (1635); reflecting the object beam from an object (1640); focusing the reference beam and the object beam at a focal plane of a digital recorder (1655) to form an off-axis hologram; digitally recording and Fourier-transforming the off-axis hologram. A method of writing an off-axis hologram includes: passing a laser beam (1950) through a spatial light modulator (1975); and focusing the laser beam at a focal plane of a photorefractive crystal (1995) to impose a hologram. A method of replaying an off-axis hologram includes: illuminating a photorefractive crystal having a hologram with a replay beam (1915).

IPC分类号： G01T1/29
摘要： A method for ultra-high resolution computed tomography imaging, comprising the steps of: focusing a high energy particle beam, for example x-rays or gamma-rays, onto a target object; acquiring a 2-dimensional projection data set representative of the target object; generating a corrected projection data set by applying a deconvolution algorithm, having an experimentally determined a transfer function, to the 2-dimensional data set; storing the corrected projection data set; incrementally rotating the target object through an angle of approximately 180°, and after each the incremental rotation, repeating the radiating, acquiring, generating and storing steps; and, after the rotating step, applying a cone-beam algorithm, for example a modified tomographic reconstruction algorithm, to the corrected projection data sets to generate a 3-dimensional image. The size of the spot focus of the beam is reduced to not greater than approximately 1 micron, and even to not greater than approximately 0.5 microns.
