Abstract: A polarized Raman Spectrometric system for defining parameters of a polycrystaline material, the system comprises a polarized Raman Spectrometric apparatus, a computer-controlled sample stage for positioning a sample at different locations, and a computer comprising a processor and an associated memory. The polarized Raman Spectrometric apparatus generates signal(s) from either small sized spots at multiple locations on a sample or from an elongated line-shaped points on the sample, and the processor analyzes the signal(s) to define the parameters of said polycrystalline material.

Abstract: A system and method for imaging a sample using Raman spectrometry. Optical fibers having opposite first ends and second ends are arranged with the first ends and second ends in respective two-dimensional arrays. The two-dimensional arrays maintain relative positions of the optical fibers to one another from the first ends to the second ends in a way that the first end of each optical fibers of the bundle can simultaneously collect a corresponding Raman signal portion scattered from specific spatial coordinates of the area of the sample. The so-collected Raman signal portions are propagated towards the corresponding second end, from which are outputted and detected simultaneously using an array of detectors.

Abstract: An optical module includes a wavelength variable interference filter having a fixed reflective film, a movable reflective film which faces the fixed reflective film with a gap between reflective films interposed therebetween, and an electrostatic actuator that changes the gap between reflective films, and a gap control unit that controls the electrostatic actuator. The gap control unit controls the electrostatic actuator on the basis of an order which is set in accordance with a wavelength to be measured, and changes the gap between the reflective films.

Abstract: Devices, systems and methods for use in confocal imaging systems are described that enable lateral and axial scans at high speeds and without a moving scanner while producing high quality images. One chromatic confocal optical head includes an illumination source, such as an addressable point source array, to provide a wide spectrum illumination including multiple wavelengths. The optical head also includes a beamsplitter to allow the light to be directed toward an object, to receive the reflected light from the object and to direct the reflected light toward a detector. The optical head further includes a pinhole mask that is positioned to receive the light that is reflected from the object after passing through the beamsplitter, and a dispersion element that is positioned to receive the light after passing through the pinhole mask, and to separate the light into multiple spectral components for reception by the detector.

Abstract: An ATR scanner and method for calibrating the same are disclosed. The scanner includes an ATR objective having a reflecting face and an optical port adapted to receive a first light beam, and to focus the first light beam to a point, at a location on the reflecting face such that the first light beam is reflected by the reflecting face and no portion of the first light beam strikes the reflecting face at an angle greater than the critical angle. A detector measures an intensity of light reflected from the reflecting face. A controller controls the location of the focal point and determines an intensity of light that was incident on the reflecting face as a function of the position on the reflecting face and an intensity of light that was reflected from the reflecting face as a function of position on the reflecting face.

Abstract: A system and method include a wavelength shift correction light source emitting wavelength shift correction emission-line light and a spectrometer including: a spectroscopic unit receiving with photoelectric conversion elements rays of dispersed spectral light obtained by dispersing incident light based on wavelength, and outputs electrical signals corresponding to light intensities of the rays of dispersed spectral light; and a unit that measures temperature of the spectroscopic unit. When the wavelength shift correction emission-line light is measured as the incident light with the spectrometer, this system and method determine wavelength shift correction time emission-line wavelength corresponding to wavelength shift correction emission-line light, based on electrical signals from photoelectric conversion elements receiving wavelength shift correction emission-line light, and the measured temperature. The system and method determine wavelength variation from the difference between determined wavelength shift correction time emission-line wavelength and known emission-line wavelength of the wavelength shift correction emission-line light.

Abstract: Presented herein are systems and methods directed to a multispectral absorption-based imaging approach that provides for rapid and accurate detection, localization, and quantification of gas leaks. The imaging technology described herein utilizes a scanning optical sensor in combination with structured and scannable illumination to detect and image spectral signatures produced by absorption of light by leaking gas in a quantitative manner over wide areas, at distance, and in the presence of background such as ambient gas and vapor. Moreover, the specifically structured and scannable illumination source of the systems and methods described herein provides a consistent source of illumination for the scanning optical sensor, allowing imaging to be performed even in the absence of sufficient natural light, such as sunlight. The imaging approaches described herein can, accordingly, be used for a variety of gas leak detection, emissions monitoring, and safety applications.
