Method And Device For Measuring The Concentration Of Substances In Gaseous Or Fluid Media Through Optical Spectroscopy Using Broadband Light Sources

Номер: US20120006098A1
Автор: Elfred Lewis, Hartmut Ewald, Martin Degner, Nils Damaschke
Принадлежит: Bluepoint Medical GmbH and Co KG

The invention relates to a method and to a device for using partially non-stabilized broadband light sources to accurately measure partially broadband-absorbing substances using referencing measuring cells. In order to create a low-cost, high-resolution, and at the same time fast spectrographic device for measuring concentrations of substances in fluid or gaseous media that is also suitable for harsh environments, the light radiated by the broadband light sources ( 1 ) through light guiding optical systems is fed through the measuring section of the self-referencing measuring cell ( 20, 30, 40 ) or only partially through a measuring cell ( 10 ) to a measurement detector (photoreceptor 11 ) and partially through a reference path (optical waveguide 8 ) to a reference detector (photoreceptor 15 ), and a mode coupler ( 5, 9, 14 ) is associated with each optical waveguide ( 2, 4, 7, 8 ) in order to homogenize the radiation characteristic of the broadband light sources ( 1 ), which varies over time and space.

Methods are presented for separating the effects of background doping density and effective minority carrier lifetime on photoluminescence (PL) generated from semiconductor materials. In one embodiment the background doping density is measured by another technique, enabling PL measurements to be analysed in terms of effective minority carrier lifetime. In another embodiment the effective lifetime is measured by another technique, enabling PL measurements to be analysed in terms of background doping density. In yet another embodiment, the effect of background doping density is removed by calculating intensity ratios of two PL measurements obtained in different spectral regions, or generated by different excitation wavelengths. The methods are particularly useful for bulk samples such as bricks or ingots of silicon, where information can be obtained over a much wider range of bulk lifetime values than is possible with thin, surface-limited samples such as silicon wafers. The methods may find application in solar cell manufacturing for improving the manufacture of silicon ingots and bricks, or for providing a cutting guide for wafering.

An aspiration chamber is provided with an aspiration aperture, having a shape in which a width becomes larger from one edge toward another edge, and aspirates soft tissue through the aspiration aperture. A deformation amount measurement portion measures aspiration deformation amounts of the soft tissue within the aspiration aperture along a virtual line from the one edge to another edge. Based on the aspiration deformation amounts that have been measured by the deformation amount measurement portion, a computer uses a finite element model of the soft tissue to derive an approximation equation according to a numerical function for the aspiration deformation amounts and positions on the virtual line and determines a distribution of elasticity from the surface of the soft tissue into its interior by substituting parameters of the approximation equation into estimation equations that are derived by assuming that the deformation along the virtual line reflects elasticity distribution parameters.

Increased Absorption-Measurement Accuracy Through Windowing of Photon-Transit Times to Account for Scattering in Continuous Webs and Powders

Номер: US20120209536A1
Автор: Michael Kon Yew Hughes, Sebastien Tixier
Принадлежит: Honeywell ASCa Inc

Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.

Принадлежит: US Department of Army

Multiple functional systems are integrated to configure a portable handheld decision-aid device for first responder medics. Fuzzy membership functions of “life” and “death” are used to determine the status of fallen people using remote measurements. EO/IR cameras can be used to detect and identify casualties in a mass injury situation, while also estimating body temperature. Using the temperature, along with the remote estimation of a second vital sign, the life membership proportion can be estimated from the ground truth by using a 2D projection of stable vital signs. The other fuzzy membership function, death, can be estimated by the presence or absence of peri-mortem and post-mortem molecules. These molecules are only released after death and provide a certain indication of death. Solid state UV laser resonance Raman backscattering from these molecules allows the device to analyze the molecules present in a plume around the casualty.

Принадлежит: Gas Sensing Solutions Ltd

An optical absorption gas sensor includes a radiation source, detector and a radiation guide. The radiation source and detector are close together and in thermal communication. The radiation guide has a rectangular cross section and curves in a first sense, around an axis parallel to the major dimension of the rectangular cross section, and then in a second opposite sense, and again in the first sense. A relatively long path for radiation is provided in a compact device, without the attenuation of radiation which would occur if the radiation guide did not have a rectangular cross section and curved only around an axis parallel to the major dimension of the rectangular cross section. A reference measurement can be obtained by mounting a reference radiation source behind a translucent measurement radiation source and directing radiation from the reference radiation source through the measurement radiation source. Radiation from a reference radiation source may be directed around the measurement reference source. Measurement and reference signals can be obtained by using a light emitting diode to generate radiation which is detected by a photodiode, in a first operating mode, and driving the photodiode to generate radiation having a different emission spectrum while detecting the resulting radiation using the light emitting diode, in a second operating mode. An optical absorption gas sensor may be manufactured by abutting two or more L-shaped radiation guide portions to form a radiation guide. The radiation guide has an interior surface operable to reflect radiation emitted by the radiation source of the optical absorption gas sensor.

Dynamic signal extension in optical detection systems

Номер: US20130119277A1
Автор: Bernhard Schinwald, Josef J. Atzler
Принадлежит: Molecular Devices LLC

Systems and methods for measuring a target in a sample, the target being capable of generating an emitted light in response to an excitation light. In an example system, an excitation light source generates the excitation light along an excitation optical path. An attenuation filter arrangement selectively adds an attenuation filter to the excitation optical path. The attenuation filter attenuates the excitation light by a corresponding attenuation factor. The excitation light exits the attenuation filter arrangement along the excitation optical path to illuminate the sample. A light energy detector receives the emitted light generated in response to the excitation light, and outputs a measured signal level corresponding to an emitted light level. If the light energy detector indicates an overflow, signal measurement is repeated with attenuation filters of increasing attenuation factors until the measured signal level does not overflow.
