Abstract:
An Internet-based integrated technology platform that simultaneously supports the management of Public Information Sites—Web sites used to both (1) inform the public; and (2) capture and manage public comment (including submission of images—while at the same time providing support for electronic communication for project teams that manage public involvement projects. The support includes sharing of graphic, text and collaborative tasks. The system and method allow revisions to comments and dynamic feedback in agency decision making based on comments with greater responsiveness. The system is also suited for implementing charettes with a large number of participants.

Abstract:
The objective of the invention is to provide a color inspection system capable of making determination on pass or failure with accuracy equivalent to that for the case of visual inspection even in the case of inspecting various textile products as measurement targets, such as a raised cloth, cloth with printed patterns such as marbled pattern, moire pattern and detailed pattern, and so forth. With a color inspection system, an illuminant is set to shine light on the surface of a textile product M placed on the top surface of a measuring platform to thereby make measurements from a direction at an angle of 45 degrees from the surface of a measuring region of the textile product M by use of a spectroradiometer of a measuring unit. The spectroradiometer is provided with a wide range lens attached thereto to thereby expand a measuring region. The results of measurement by the spectroradiometer are inputted to an information processor of a determination unit. The information processor computes color values for the whole measuring region to be compared with standard color values stored in a memory to thereby make determination on pass or fail.
Abstract:
Computed tomography imaging spectrometers (“CTISs”) employing a single lens are provided. The CTISs may be either transmissive or reflective, and the single lens is either configured to transmit and receive uncollimated light (in transmissive systems), or is configured to reflect and receive uncollimated light (in reflective systems). An exemplary transmissive CTIS includes a focal plane array detector, a single lens configured to transmit and receive uncollimated light, a two-dimensional grating, and a field stop aperture. An exemplary reflective CTIS includes a focal plane array detector, a single mirror configured to reflect and receive uncollimated light, a two-dimensional grating, and a field stop aperture.
Abstract:
An optical spectrometer and/or a method of optical spectroscopy is described herein. One exemplary spectrometer includes a planar spectral filter, a dispersion system, and a detector array having at least two dimensions. The planar spectral filter filters incident light to generate a plurality of wavelength dependent spatial patterns. The dispersion system disperses the spatial patterns along at least one dimension in a wavelength dependent fashion onto the detector array. As a result, spatial patterns corresponding to different wavelengths are centered at different locations on the detector array. The dispersed spatial patterns superimpose at the detector array in an offset but overlapping relationship, creating an asymmetric image that facilitates the spectral analysis of a wide range of light sources, including diffuse or spectrally complex light sources.
Abstract:
A fiberscope device is disclosed which is suitable for video imaging, laser Raman spectroscopy and laser Raman spectroscopic (i.e. chemical) imaging. The fiberscope design minimizes fiber background interference arising from the laser delivery fiber optic and the coherent fiber optic light gathering bundle while maintaining high light throughput efficiency through the use of integrated spectral filters. In the fiberscope design, the laser delivery fiber optic is offset from the coherent fiber optic light gathering bundle. The laser delivery field is captured entirely by the light gathering field of view of the coherent fiber bundle. The fiberscope incorporates spectral filter optical elements that provide environmental insensitivity, particularly to temperature and moisture. The fiberscope is suited to the analysis of a wide range of condensed phase materials (solids and liquids), including the analysis of biological materials such as breast tissue lesions and arterial plaques, in such a manner to delineate abnormal from normal tissues.
Abstract:
A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated color of a structure is also provided.
Abstract:
A method for detecting disease in a patient includes providing infrared (IR) light and coupling the IR light through direct lens coupling or through a first group of one or more optical fibers. IR light is reflected from a portion of the patient and collected by a lens arrangement or a second group of one or more optical fibers. The reflected IR light is dispersed into its spectrum which is detected and analyzed. An apparatus suitable for diagnosing a disease in a patient includes an IR light source and optical fiber or direct lens coupling of IR light onto a body part or fluid of the patient. Reflected light from the patient is optically dispersed using a prism or grating. An IR focal plane array receives the optically dispersed light. The spectrum of the reflected IR light is used to provide a diagnosis of disease in the patient by identifying various disease markers or chemical fingerprints. The method and apparatus are capable of non-invasively detecting disease markers in a patient.
Abstract:
A spectroscopic system which determines a property of a biological structure in a volume of interest of a person includes a low cost objective lens for directing an excitation beam into a volume of interest and for collecting return radiation from the volume of interest. After detection of the return radiation and generation of spectroscopic signals, a correction unit performs a compensation for aberrations of the spectroscopic signals introduced by the low cost objective lens. Since the aberrations of the objective lens strongly depend on the lateral distance of the volume of interest from the optical axis of the objective lens, the correction unit uses a correction table providing an assignment between correction values and various lateral positions of the volume of interest.
