摘要： A laser beam is reflected by a light beam scanning device and irradiated onto a hologram recording medium. On the hologram recording medium, an image of a linear scatter body is recorded as a hologram by using reference light that converges on a scanning origin. The light beam scanning device bends the laser beam at the scanning origin and irradiates the laser beam onto the hologram recording medium. At this time, by changing a bending mode of the laser beam with time, an irradiation position of the bent laser beam on the hologram recording medium is changed with time. Diffracted light from the hologram recording medium produces a reproduction image of the linear scatter body on a light receiving surface of the stage. When an object is placed on the light receiving surface, a line pattern is projected by hologram reproduction light, so that the projected image is captured and a three-dimensional shape of the object is measured.

摘要： An apparatus for the recording and multiplexing of pulsed reflection holograms made possible with the invention of the Hollow Core Photonic Crystal Fiber is disclosed herein. This holographic imaging apparatus uses the Hollow Core Photonic Crystal Fiber as a waveguide in which the highly coherent property of the lightwave required for recording interference fringes can propagate through this waveguide without this coherency of the lightwave diminishing. This apparatus enables the multiplexing of several reflection holograms in a single recording medium using the reference beam with several object beams in sequenced intervals of time and space; several multiplexed recordings are made within a brief interval in time with the object beam-emanating from incremental points in space; around a 120 degree tangential arc in space to achieve parallax around this 120 degree tangential arc. This disclosure makes possible apparatus which is transportable and shoulder mountable for pulsed reflection holography.

摘要： A method and system for use in reconstruction and retrieval of phase information associated with a two-dimensional diffractive response are presented. The method comprising: providing (75) input data indicative of one or more diffractive patterns corresponding to diffractive responses from one or more objects (50). Dividing (130) said input data into a plurality of one-dimensional slices and determining (140) one-dimensional phase data for at least some of said one-dimensional slices. Tailoring (150) the reconstructed phase data of said one-dimensional slices to form a two-dimensional phase solution. The two-dimensional phase solution is defined by phase shifts of said reconstructed one-dimensional phase data of said one-dimensional slices. The two-dimensional phase solution thus enables obtaining two-dimensional reconstructed phase data suitable for reconstruction of image data (250).

摘要： The layered generation of at least one volume grating in a recording medium by way of exposure, the recording medium having at least one photosensitive layer which is sensitized for a presettable wavelength of the exposure light. Each volume grating is generated in the recording medium by at least two wave fronts of coherent light capable of generating interference, the wave fronts being superposed in the recording medium at a presettable depth, at a presettable angle and with a presettable interference contrast. The depth and the thickness of the refractive index modulation and/or transparency modulation of a volume grating in the recording medium is controlled by depth-specific control of the spatial and/or temporal degree of coherence of the interfering wave fronts in the direction of light propagation.

摘要： The image observation apparatus introduces an object light, which is at least part of an object illumination light emitted from a light source and projected onto an object and which is reflected by the object, through a first optical waveguide to an image sensor, introduces a reference light, which is emitted from the light source and passes through an optical path different from that of the object light, to the image sensor, and records an interference fringe through the image sensor as a hologram. The apparatus forms the recorded hologram on a spatial light modulator and illuminate the modulator with a hologram illumination light corresponding to the reference light to generate a reconstruction light, and causes the reconstruction light entering a second optical waveguide optically equivalent to the first optical waveguide and exiting from the second optical waveguide to form an object reconstructed image.

摘要： The imaging apparatus includes an optical system dividing light into object and reference beams and causing the object beam and the reference beam to interfere with each other to form interference fringes on an image sensor. A processor performs multiple imaging processes for the interference fringes with different incident angles of the object beam to an object, a first process to acquire a transmitted wavefront for each incident angle and a second process to calculate a three-dimensional refractive index distribution from the transmitted wavefronts. The apparatus includes a modulator changing a phase distribution of light in any one of an optical path from a light source to a dividing element, a reference beam path and an optical path from a combining element to the image sensor and causes the modulator to change the phase distribution in at least one of the multiple imaging processes.
