Abstract:
Technologies are described for providing optical analysis systems using an integrated computational element that has a surface patterned to selectively reflect or transmit different wavelengths by differing amounts across a spectrum of wavelengths. In one aspect, a measurement tool contains an optical element including a layer of material patterned so that the optical element selectively transmits or reflects, during operation of the measurement tool, light in at least a portion of a wavelength range by differing amounts, the differing amounts being related to a property of a sample. The wavelength range can include wavelengths in a range from about 0.2µm to about 100µm. Additionally, the sample can include wellbore fluids and the property of the sample is a property of the wellbore fluids.
Abstract:
An alignment device having two angular degrees of freedom is provided. The alignment device is adjustable such that it is suitable for aligning a first apparatus with respect to a second apparatus. The first apparatus may emit one or more of electromagnetic waves, acoustic waves and matter towards the second apparatus and for detection by the second apparatus. The first and second apparatuses may be disposed in a harsh environment such as is found in the vicinity of an industrial process stack. In some embodiments the first apparatus is a laser, preferably a tunable diode laser, and the second apparatus is a receiver incorporating a detector. In these embodiments the apparatuses may be used to perform laser absorption spectroscopy on a process gas flowing through an industrial process stack.
Abstract:
Devices to detect a substance and methods of producing such a device are disclosed. An example device to detect a substance includes a housing defining a first chamber and a substrate coupled to the housing. The substrate includes nanostructures positioned within the first chamber. The nanostructures are to react to the substance when exposed thereto. The device includes a first heater positioned within the first chamber. The heater is to heat at least a portion of the substance to ready the device for analysis.
Abstract:
The present invention relates to nanocompounds comprising a charge-transfer complex of at least two different size metal atomic quantum clusters (AQCs) and the use thereof as luminescent nanocompounds, particularly for the use thereof as fluorescent nanocompounds; as well as the method for obtaining and detecting them.
Abstract:
A can body inspection apparatus which prevents a drop in resistance to noise while enabling high speed inspection is provided. It is comprised of a light source control means (21, 22) for turning on the light source unit a predetermined number of times of two times or more at predetermined timings at which light can be taken in by the light-detection unit through the open end face of the can body W which is moving along the path of conveyance W, a detection signal integrating means 23 for integrating signal values based on the detection signal which is output from the light-detection unit 15 due to on operations of the light source unit 10, and a condition judging means 24 for using an integrated value which is obtained by the detection signal integrating means 23 as the basis to judge the condition of the can body.
Abstract:
An examination apparatus 1 for microorganisms for measuring an amount of microorganisms in a sample solution, the apparatus including stirring and mixing means 7 for stirring and mixing the sample solution into which a sample and a fluorescent staining reagent are added, in a sample container 5 formed of a material allowing light to pass through, an excitation light source 10 including a light source that irradiates an irradiation target surface of the sample container 5 with excitation light while the sample solution is being stirred by the stirring and mixing means 7, light receiving means 14 for detecting light and converting the light resulting from a fluorescent emission caused by excitation light from the excitation light source 10, into an electric signal, and control means 23 for detecting the number of emissions based on the electric signal from the light receiving means 14 and calculating the amount of the microorganisms contained in the sample in the sample container 5 based on the number of emissions.
Abstract:
Ein Verfahren zur Untersuchung eines oder mehrerer Phasenobjekte (4; 33; 233) wird beschrieben, bei dem ein Gitter aus Elementen (10) verwendet wird, das mit Licht (20) einer Lichtquelle (37) beleuchtet wird, dessen Kohärenzlänge größer als der mittlere Abstand benachbarter Elemente des Gitters ist. Ein Beugungsbild des an dem Gitter gestreuten Beleuchtungslichts (25) wird erzeugt, wobei das eine oder die mehreren Phasenobjekte (4; 33; 233) im Lichtweg zwischen der Lichtquelle (37) und dem Gitter und/oder im Lichtweg des an dem Gitter gestreuten Beleuchtungslichts platziert sind. Zumindest ein Teil des Beugungsbildes wird direkt oder nach Wechselwirkung mit weiteren optischen Komponenten von einem optischen Detektor (38) detektiert und in ein Signal umgewandelt. Das Signal wird weiter analysiert, um daraus Informationen bezüglich des einen oder der mehreren Phasenobjekte zu ermitteln. Eine entsprechende Vorrichtung wird ebenfalls beschrieben.
