摘要： An apparatus for imaging a includes an light source for illuminating the sample simultaneously in a line focus or an array of foci; and a sensor for detecting photons emitted or scattered from the sample simultaneously in an array of fields of view. An array of sub-observation volumes in the sample, from which photons are emitted or scattered during imaging, is defined by the volumes in space where the line focus or array of foci from the light source overlap with the corresponding array of field of views of the sensor. A cylindrical sample holder holds the sample at a surface and is rotatably arranged such that at least a portion of the sample can be transported through at least one of the sub-observation volumes by rotating the sample holder. The apparatus can be used in a high-throughput method of imaging.

摘要： Methods and systems for etching substrates using a remote plasma are described. Remotely excited etchants are formed in a remote plasma and flowed through a showerhead into a substrate processing region to etch the substrate. Optical emission spectra are acquired from the substrate processing region just above the substrate. The optical emission spectra may be used to determine an endpoint of the etch, determine the etch rate or otherwise characterize the etch process. A weak plasma may be present in the substrate processing region. The weak plasma may have much lower intensity than the remote plasma. In cases where no bias plasma is used above the substrate in an etch process, a weak plasma may be ignited near a viewport disposed near the side of the substrate processing region to characterize the etchants.

摘要： An analysis (e.g., LIBS) system includes a source of radiation, an optical emission path for the radiation from the source of radiation to a sample, and an optical detection path for photons emitted by the sample. A detector fiber bundle transmits photons to the spectrometer subsystem. At least one fiber of the fiber bundle is connected to an illumination source (e.g., an LED) for directing light via at least a portion of the detection path in a reverse direction to the sample for aligning, sample presence detection, localizing, and/or focusing based on analysis of the resulting illumination spot on the sample.

摘要： A system and method for internally inspecting a tubular composite part so as to identify and measure adhesive flow therewithin are provided, along with an endpoint adapter assembly of a near infrared (NIR) spectrometer. The system includes an end point adapter that fits within and maintains a consistent cross-sectional position within the tubular composite part. The system also includes a plurality of optical fibers extending radially outward from the end point adapter. The end point adapter moves longitudinally through the tubular composite part and receives light with the plurality of optical fibers following interaction of the light with the tubular composite part. The system further includes a NIR imaging spectrometer configured to disperse the light being collected by the plurality of optical fibers across an NIR spectrum and a NIR camera configured to generate images of the tubular composite part based on dispersed light.

摘要： An analyte-detection system has an optical waveguide with first and second cladding layers adjacent a core; a light source coupled to provide light to the waveguide; a photodetector such as a metal-semiconductor-metal, vertical PIN, or horizontal PIN photodetectors, the photodetector having an absorber configured to detect light escaping from the waveguide through the first cladding layer; multiple, separate, photocurrent collectors, where each photocurrent collector collects current from a separate portion of the photodetector absorber; and at least one current-sensing amplifier for receiving photocurrent. The photodetector absorber is an undivided absorber region for multiple photocurrent collectors. Either separate amplifiers are provided for each of the multiple photocurrent collection lines, or multiplexing logic couples selected photocurrent collectors to amplifiers, while coupling unselected photocurrent collectors to a bias generator.

摘要： A system including a light source, sampling tray, and a plurality of fiber optics positioned to achieve high contrast to improve accuracy and eliminate the need to rotate the sample. A composite light image from the fiber optics is fed to a spectrometer which converts the reflected light into a fingerprint corresponding to the concentration of at least one substance in the sample. The fingerprint is processed by a statistical model to determine concentration level of the at least one substance in the sample and the concentration level is then displayed.

摘要： A controller of an optical measurement apparatus causes, in a condition that a rotational speed of a rotary body is controlled so that the speed is a specified value, a light source to generate light having a constant intensity and apply the light to an irradiation region, and acquires first timing information based on a change with time of an intensity of reflected light or transmitted light that is output from a second detection unit receiving the reflected light or transmitted light of the applied light. The controller causes the light source to periodically generate pulsed light in accordance with the first timing information and apply the pulsed light to the irradiation region, and acquires second timing information based on a result which is output from the first detection unit whose measurement is periodically enabled in accordance with the first timing information.
