Abstract:
A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

Abstract:
The present subject matter relates to methods of high-speed analysis of product samples during production of the product. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward optical detectors. Signals from the optical detectors are compared to determine characteristics of the product under analysis. Temperature within the monitoring system may be monitored in order to provide compensation for the signals produced by the optical detectors. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.
Abstract:
A method and apparatus is disclosed for multi-mode spectral imaging. In one embodiment, the present invention comprises the steps of illuminating an object with (101) with a modified illumination profile, producing a reflected, transmitted or fluorescence image, scanning the object (104), and re-imaging (105) the reflected, transmitted or fluorescence light after modifying the light's optical state. The present invention preferably works in conjunction with other imaging systems to provide both high-spectral resolution images with lower temporal resolution and multiple image acquisition with high temporal resolution.

Abstract:
Optical systems that provide for simultaneous images and spectra from an object, such as a tissue sample, an industrial object such as a computer chip, or any other object that can be viewed with an optical system such as a microscope, endoscope, telescope or camera. In some embodiments, the systems provide multiple images corresponding to various desired wavelength ranges within an original image of the object, as well as, if desired, directional pointers that can provide both an identification of the precise location from which a spectrum is being obtained, as well as enhancing the ability to point the device.

A fluorescence spectrophotometer system may be implemented in scanning fluorescence polarization detection applications. A wavelength and area scanning fluorescence spectrophotometer system may include a light source, an excitation double monochromator, an excitation/emission light transfer module, an emission double monochromator, a high speed timer-counter circuit board, a precision positioning apparatus for positioning a sample relative to the focal plane of the excitation light, and polarizing filters at the excitation side and the emission side. The system may be operative to analyze more than one fluorescent compound in the sample; additionally or alternatively, the system enables analysis of samples from selected ones of a plurality of samples.
Abstract:
An instrument system for monitoring corona and like conditions of electrical equipment such as generators includes an optical probe (20) which receives light from a plurality of different areas in the equipment and separately conveys the light acquired from each area to a position-sensitive photoelectric converter (24). The probe includes optical fibers (22) with terminal ends disposed in spaced holes in the wall of a tubular housing. The output of the photoelectric converter (24) is analyzed to determine the presence of corona, arcing, flame ignition combustion, or smoldering conditions at each of the monitored areas in the equipment, the severity of such conditions, and the identity of materials involved in such conditions based on the intensity and spectral content of the acquired light. The photoelectric converter (24) includes a photomultiplier, a photodiode array, and means for automatically directing the acquired light to either one in accordance with its intensity.
