Abstract: Examples of a spectroscopy system with a specially design ambient illumination system are disclosed. The ambient illumination system comprises one or more light emitting diodes (LEDs) that provide illumination light in the wavelength of 400-785 nm. The ambient illumination system can further comprise a filter to block light above 785 nm. The filter can be placed directly in front of LED emitters. The LEDs can be white LEDs or RGB LEDs. The spectroscopy system can further comprise a control system that can receive a signal from the spectral probe when the spectral measurements commence and can instantaneously send a signal to automatically switch off the ambient illumination system and to receive a signal from the spectral probe when the spectral measurements are terminated and automatically switch on the ambient illumination system. Examples of methods of operating the spectroscopy system and the ambient illumination system are disclosed.

Abstract: Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.

Abstract: A method of interrogating an absorbing sample includes using a mode-locked laser mode-locked in both a clock-wise (CW) and a counter-clock wise (CCW) direction to generate first and second optical pulses having different repetition rates. One of the first and second optical pulses is directed in a CW direction and the other of the first and second optical pulses is directed in the CCW direction. The first optical pulses are transmitted through the absorbing sample to probe the absorbing sample while the second optical pulses are transmitted through the absorbing sample to act as a local oscillator. An interference pattern produced by interference between the first and second optical pulses is detected after traversing the absorbing sample.

Abstract: There are provided an atomic absorption photometer and an atomic absorption measurement method which can easily perform background correction in a short time period by using a plurality of types of methods while suppressing the amount of samples consumed. Background correction is performing by using each of the D2 lamp method, the Zeeman method, and a self-reversal method, according to measurement data in each of measurement periods T41 to T46 obtained in one data acquisition cycle. Background correction is performed on the common measurement data (atomic absorption data) obtained in the atomic absorption measurement period T41, by using the measurement data (background data) obtained in each of the first to third background measurement periods T44, T46, and T42.

Abstract: An imaging device includes laser diodes (LDs) generating near-infrared wavelength light, lenses configured to deliver the light to tissue, a first receiver having one or more detectors, and a first part with at least one of the LDs capable of being pulsed. The first receiver receives light reflected from the tissue and is synchronized to the pulsed light and configured to perform a time-of-flight measurement. An infrared camera receives light reflected by the tissue from a second part of the imaging device. The camera captures light while the second part is off, and while the second part is on to generate corresponding signals, and differences the signals to generate an image. An array of LDs generates a grid of spots on the tissue, which is reflected to the camera. A coupled phone, tablet, or computer receives and processes the time-of-flight measurement, the image, and the reflected grid of spots.
