Technical Examples
- A hologram imaging device for obtaining hologram images and associated document markings which are commonly being used for document verification is disclosed. The imaging device comprises a housing defining an imaging chamber, camera, hologram light source, document light source and imaging platform. The hologram light source consists of a series of illumination devices (e.g., LEDs) adjustably mounted in an arc or semicircular arrangement. An LED controller regulates the state of the LEDs by controlling whether each LED is on or off and adjusting the intensity of each LED in an on position. During use, a document is secured within the housing by the imaging platform such that a hologram or other document marking is positioned beneath a camera lens. Then, the LEDs of the hologram light source are regulated by the LED controller such that different images and/or colors of the hologram may be captured by the camera. Consequently, a series of images and/or colors of the hologram are captured without the requirement of moving the hologram, camera or LED array during the process.
- Hologram production techniques can combine source data representing realistic information describing an environment with source data providing representational information describing a feature of the environment and/or some object interacting with the environment. The combined data is used to produce holograms, and particularly holographic stereograms including features that enhance the visualization of the environment depicted in hologram. A haptic interface can be used in conjunction with such holograms to further aid use of the hologram, and to provide an interface to secondary information provided by a computer and related to the images depicted in the hologram.
- A holographic printer is disclosed which produces an intermediate hologram H3 and uses the intermediate hologram H3 to produce a white light viewable hologram H2.
- A simplified method is provided for recording identification information, such as a serial number or the like, in a hologram-recorded film simultaneously with hologram duplication. The method includes the steps of coupling a hologram recording film with a master hologram plate having a master hologram, the master hologram plate having a reflective area adjacent the master hologram; and directing laser beams towards the master hologram plate to induce interference between incident laser light and diffraction laser light from the master hologram in the recording film, at least some of the laser beams radiating the reflective area through a transmission type controllable display device to record a pattern in the hologram recording film corresponding to a pattern displayed at the transmission type controllable display device.
- A method of generating a binary computer generated hologram for use in displaying a holographic image, the method comprising the steps of generating a complex modulation computer generated hologram corresponding to a desired reply object, transforming the complex modulation computer generated hologram into a real positive computer generated hologram, and transforming the real positive computer generated hologram into a binary computer generated hologram by comparing each element of the real positive computer generated hologram with at least one neighboring element and replacing the compared element with a binary value which depends upon the result of the comparison.
