摘要： Systems and methods for detecting an optically variable material are provided, According to an illustrative embodiment, a method for detecting an optically variable material includes capturing a first image of al least a portion of a document while the at least a portion of the document is subjected to a first electromagnetic radiation from a first angle of incidence, and capturing a second image of at least a portion of the document while the at least a portion of the document is subjected to a second electromagnetic radiation from a second angle of incidence, The first angle of incidence is different from the second angle of incidence. The first and second images are captured by an imaging device that has a substantially fixed position. The method also includes comparing the first image to the second image to determine whether an optically variable material is present on the document.

摘要： The present invention provides a method and system for imaging documents such as bank notes The method comprises passing a document past an image sensor such as a line scan camera while sequentially illuminating the document using multi-mode illumination. Two or more light sources are used, each one producing a different mode of illumination. A lookup table divides documents into discrete successive sections (i e. scan lines) and specifies a mode of illumination (e.g., color, azimuth, reflective, transmissive) for each section of a document during imaging. As the document passes the image sensor, the light sources are activated according to the sequence specified in the lookup table, producing an interleaved, multi-mode image of the document.

摘要： Systems and methods for authenticating a document are provided. In one embodiment, a method for authenticating a feature of a document includes capturing a first image of a region of a document while the region is subjected to a first wavelength of electromagnetic radiation. The region includes at least a portion of the document. The method also includes determining a first intensity value associated with the first image of the region, and comparing the first intensity value with a first training intensity value of a region of a training document. The first training intensity value is obtained using the first wavelength of electromagnetic radiation. The method also includes determining whether the document is authentic at least partially based on the comparison between the first intensity value and the first training intensity value.

摘要： Document inspection system comprising a transport system for transporting documents along a transport path (12) through an inspection station. At least one ultrasonic inspection apparatus at the inspection station, the apparatus including ultrasonic transmitting and receiving transducers (42,44) arranged on opposite sides of the transport path, and a processing system for monitoring ultrasonic signals received by the receiving transducer. An ultrasonic absorbing material (300) is provided around the transducers and facing the transport path for absorbing ultrasound reflected by a document. Document guide apparatus (312,314), having a lower coefficient of friction than the absorbing material, extends partially over the absorbing material (300) so as to prevent documents contacting the absorbing material in use while leaving the absorbing material exposed to the transport path at least adjacent the transducers.
