摘要： A marking system for use with a multi-spectral imager for use in high throughput sortation of articles having distorted or irregular surfaces is disclosed. Specific uses include, but are not limited to, document sorting, garment and textile rental operations, laundry operations, and mail and package sorting and identification. Methods and apparatus are provided to remotely identify items via information that is wavelength-encoded within an applied mark, as well as a mark reading/decoding scheme. In the preferred embodiment the marks are multi-dimensional. In one preferred embodiment the marks are used to realize multi-dimensional wavelength enabled coding schemes. The marks can be overlayed one upon another and/or they can contain one or more key regions having at least one predetermined spectral characteristic for providing information related at least to reading and/or decoding the marks.

摘要： Cholesteric liquid crystals in microencapsulated form are applied as a background or as printed information as a part of a reversible information carrying system. The reversible information system is normally invisible under ambient conditions, while providing a highly contrasting background to a dataform symbology upon stimulation with appropriate forms of at least one of heat and light. The reversible information system is adapted for the demands of automated sorting systems.

摘要： A random laser system includes critical Solution Temperature (CST) material, either a Lower CST (LCST) or an Upper CST (UCST) material, in combination with an optical gain medium (20), such as a laser dye. A laser-like emission is observed in response to optical pumping (12) only when the CST material is in a scattering state. The random laser is suitable for being microencapsulated (10), and can be used for, as examples, remote temperature (14) sending applications as well as for visual display applications.

摘要： Methods and apparatus for providing markings on objects, such as optical media (420) which do not interfer with the functionality of the object. The optical media (420) may have a portion, such as a central clamping area (422) which does not contain information. A mark (432) is transferred into this area through the use of a photomask. The mark (432) may be viewed in several ways including by placement over a fluorescent background (414) and irradiation with a low intensity ultraviolet light (415). This technique increases the contrast of the image.

摘要： Systems and methods for document and product authentication are provided using a combination of interacting absorption and emission materials that are formed into covert optically encoded markings. The markings are formed from at least one emitter and at least one absorber, that exhibit a first emission in response to a first excitation of the emitter and a change in that emission in response to excitation of the absorber such that various combinations of emitter and absorber materials create a machine readable response that cannot be detected by the human eye.

摘要： Optical media having markings that are non-interfering, or substantially non-interfering with readout of data from the optical media are disclosed. The optical media make use of certain formulations of color forming coatings described herein. Protective coatings used to enhance the color forming coatings are also presented. Methods for incorporating the coatings into the optical media are included. In preferred embodiments, the marking is formed in a photosensitive coating that is applied to the optical media, and then cured with a first light. A second light, having a substantially separate band of wavelengths from the first light, is used to image a marking into the coating. The coating is robust to many external influences, such as ambient environmental conditions, and physical wear.

摘要： A method is disclosed for limiting temperature increase of a treatment area during photodynamic therapy (PDT), whereby temperature sensitive materials in the form of a skin patch or compound are applied over the treatment area. The temperature sensitive materials are optically changing from substantially transmissive to at least one of substantially scattering, absorbing or reflecting at wavelengths used for the PDT, the change occurring upon surpassing a predetermined temperature. In preferred embodiments, the optical changes are reversible as the temperature of the temperature sensitive compounds decrease below a predetermined temperature.

Also disclosed is a method and system for detecting a presence of a foreign substance on a surface of a bill. The method includes steps of (A) illuminating at least a portion of the bill with light; in response to the light, (B) causing either a specular reflection or a diffuse reflection from a surface of the bill; (C) detecting a presence of a specular reflection; and (D) correlating the detected specular reflection with the presence of a foreign substance, such as tape, on the bill. An amount of polarization contrast can also be determined for detecting a presence of a foreign matter, such as tape, on the surface of the bill.
