ABSTRACT:
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.
