Abstract: A dynamic light scattering measurement apparatus using a phase modulation type interference method includes an optical coupler for dividing light from a low coherent light source, a converging lens for irradiating one of the divided lights to a sample 9 , phase modulators for modulating the phase of the other divided lights, a spectrum measurement means for measuring a spectrum of the interference light of the phase-modulated reference light and the scattered light outgoing from the sample, and an analyzing means for measuring the dynamic light scattering of particles of the sample based on the first order spectrum corresponding to the basic frequency of the phase-modulating signal or a higher order spectrum corresponding to a frequency equal to two, three or the like times the basic frequency appearing in the interference light spectrum measured by the spectrum measurement means. An amount s/L obtained by normalizing the light path length s within the sample by the mean free path L of the particles is set to be not more than 3. Dynamic properties of a high concentration medium can be measured with high precision based on the scattered light from such medium.

Abstract: The invention relates to a mobile remote detection device for accumulations of methane, comprising an emitter device having a light source in order to generate air, the wave length of said light source being synchronised with t he spectral signature of methane, whereby the light can be directed towards a measuring field. Said detection device also comprises a detector device for detecting backscattered light, and an evaluation device. The aim of the invention is to improve said remote detection device in such a manner that i t has a high degree of measuring sensitivity with a compact and stabile structure. According to the invention, the light source generates light at a wave length of between 3200nm and 3300nm at which methane is absorbed and th e light source has an optical parametric oscillator with seed-injection, said oscillator being associated with a pump laser which is operated in seed- injection mode.

Abstract: A method of fluorescence measurement on analytes, marked with different fluorescent markers, which have spectrally different fluorescence emissions, in a sample is described, having the following steps: illumination of the sample in the measurement volume using a laser to excite the fluorescence emission of the at least two fluorescent markers, the illumination of the measurement volume being performed with a maximum of one single laser line, having an excitation intensity sufficiently high that the fluorescent markers are jointly excited through 2-photon absorptions, detection of the fluorescence emission using at least two detector devices which are designed for light detection in different spectral ranges in accordance with the spectral fluorescence properties of the fluorescent markers, and performance of a cross-correlation and/or coincidence analysis of detector signals of the detector devices. A measurement device for performing the method is also described.

Abstract: The invention concerns a device and a method for measuring a sample (2) by correlation spectroscopy. The device comprises a confocal microscope (1) including a focusing optical system (4) whereof the field (7) defines a collecting volume (9). A light source (10) produces an excitation beam (8) which is reflected towards means (11) for directing it on the sample (2) through the microscope. The measuring device also comprises means for detecting (14) the intensity of the light flux (13) produced by the interaction of the excitation beam (8) on the sample and collected by the microscope and means for processing (15) the signal produced by the detection means (14). A photonic structure (24) increasing the collected light flux (13) is arranged at the focal point (7) of the microscope focusing optical system (4) or combined with said focal point (7) by an optical element (29) to form interference bands (25) in the collecting volume (9).

Abstract: The optical system has a lens array (21-23) and a field lens (5) to project an array (11-13) of objects on a detector array (61-63). A telescope lens (41,42) is between the lens array (21-23) and the field lens (5) and between the field lens and the detector array (61-63). An array of micro-lenses is in front of the detector array (6). An illuminating light system can be integrated into the optical system. A diaphragm aperture array (3) is between the lens array (21-23) and the field lens (5). The objects are shown as a filled microtitration plate (1) containing the samples under study or a substance chip. The system is a reader for micro-titration plates with absorption, fluorescence including fluorescent correlation spectroscopy or luminescence. An Independent claim is included for a spectrophotometer.

Abstract: A spectrometer (10) includes a two-dimensional array of modulatable micro-mirrors (18), a detector (20), and an analyzer (22). The array of micro-mirrors is positioned for receiving individual radiation components forming a part of an input radiation source. The micro-mirrors are modulated at different modulation rates in order to reflect individual radiation components therefrom at known and different modulation rates. The micro-mirror array combines a number of the reflected individual radiation components and reflects the combined components to the detector. The detector is oriented to receive the combined radiation components reflected from the array and is operable to create an output signal representative thereof. The analyzer is operably coupled with the detector to receive the output signal and to analyze at least some of the individual radiation components making up the combined reflection. By using a micro-mirror that receives individual radiation components and then modulates the radiation components at different rates, all of the radiation components can be focused onto a single detector to maximize the signal-to-noise ratio of the detector. A variable band pass filter spectrometer, variable band reject filter spectrometer, variable multiple band pass filter spectrometer, and a variable multiple band reject filter spectrometer utilizing the same invention are also disclosed.
