摘要： An anticounterfeiting device comprising a surface relief structure having both diffractive and polarizing properties. Polarization of reflected light is controlled by the orientation and composition of a fine grating structure whose shortest period is substantially smaller than the wavelength of visible light; and diffraction is controlled by a longer period component of the grating structure having a second orientation. Presence and arrangement of the polarizing properties of the device are detected by illuminating the device with polarized light and viewing the reflected light, or by illuminating the device with unpolarized light and viewing reflected light through a polarizer. Because such a device is difficult to copy or reverse engineer precisely, the authenticity of the device can be judged by the presence and arrangement of the polarization properties and the diffraction properties in the device.

摘要： An apparatus for detecting a hidden image, which is formed in a first area of a hologram, is disclosed. The apparatus has a laser device for generating a laser beam and projecting the laser beam to the hologram, and a sensing device for sensing light that reflects from the hologram. When the laser beam is emitted to the hologram at a first incident angle, at least one diffractive beam is generated by diffraction of the laser beam. The sensing device is capable of outputting a responding signal according to the characteristics of the diffractive beam. Additionally, if the laser beam is emitted to the hologram at an incident angle, which is not equal to the first incident angle, the diffractive beam cannot be generated so that the sensing device does not output the responding signal.
摘要翻译：公开了一种用于检测形成在全息图的第一区域中的隐藏图像的装置。该装置具有用于产生激光束并将激光束投射到全息图的激光装置，以及用于感测从全息图反射的光的感测装置。当激光束以第一入射角发射到全息图时，通过激光束的衍射产生至少一个衍射光束。感测装置能够根据衍射光束的特性输出响应信号。此外，如果激光束以不等于第一入射角的入射角发射到全息图，则不能产生衍射光束，使得感测装置不输出响应信号。

摘要： A illumination device sequentially projects a selective set of spatially encoded intensity light pulses toward a scene. The spatially encoded patterns are generated by an array of diffractive optical or holographic elements on a substrate that is rapidly translated in the path of the light beam. Alternatively, addressable micromirror arrays or similar technology are used to manipulate the beam wavefront. Reflected light is collected onto an individual photosensor or a very small set of high performance photodetectors. A data processor collects a complete set of signals associated with the encoded pattern set. The sampled signals are combined by a data processing unit in a prescribed manner to calculate range estimates and imaging features for elements in the scene. The invention may also be used to generate three dimensional reconstructions.

摘要： Temporal processing for realtime human vision system behavioral modeling is added at the input of a spatial realtime human vision system behavioral modeling algorithm. The temporal processing includes a linear and a non-linear temporal filter in series in each of a reference channel and a test channel, the input to the reference channel being a reference image signal and the input to the test channel being a test image signal that is an impaired version of the reference image signal. The non-linear temporal filter emulates a process with neural attack and decay to compensate for a shift in peak sensitivity and for frequency doubling in a spatio-temporal sensitivity function. The linear temporal filter accounts for the remaining subtleties in the spatio-temporal sensitivity function.

摘要： An imaging system, methodology, and various applications are provided to facilitate optical imaging performance. The system includes a sensor having one or more receptors and an image transfer medium to scale the sensor and receptors in accordance with resolvable characteristics of the medium.
