Abstract:
The analysis apparatus 10 includes a plasma generation device 11 and an optical analysis device 13. The plasma generation device 11 generates initial plasma by energizing a substance in space to be turned into a plasma state, and maintains the plasma state by irradiating the initial plasma with electromagnetic wave for a predetermined period of time. Then, the optical analysis device 13 analyzes the target substance 15 based on a time integral value of intensity of emission from the target substance 15 in an electromagnetic wave plasma region, which is maintained by the electromagnetic wave.
Abstract:
A spectrometer assembly (10), comprising an Echelle grating (18; 46) for dispersing radiation entering the spectrometer assembly (10) in a main dispersion direction, and a dispersion assembly (16; 40) for dispersing a parallel radiation bundle generated from the radiation entering the spectrometer assembly in a lateral dispersion direction, is characterized in that the dispersion assembly (16; 40) is reflective, and the dispersion assembly (16; 40) is arranged relative to the Echelle grating (18; 46) in such a way that the parallel radiation bundle is reflected in the direction of the Echelle grating. The Echelle grating (18; 46) may be arranged in such a way that the dispersed radiation is reflected back to the dispersion assembly (16; 40).
Abstract:
A multispectral imaging device for satellite observation utilizing “push broom” scanning over an observed area centered on one or more wavelengths which can be electrically controlled to produce a filtering function wavelength band, thus obviating the need for conventional stacking.
Abstract:
Embodiments of the present disclosure include an optical probe capable of communicating identification information to a patient monitor in addition to signals indicative of intensities of light after attenuation by body tissue. The identification information may indicate operating wavelengths of light sources, indicate a type of probe, such as, for example, that the probe is an adult probe, a pediatric probe, a neonatal probe, a disposable probe, a reusable probe, or the like. The information could also be utilized for security purposes, such as, for example, to ensure that the probe is configured properly for the oximeter, to indicate that the probe is from an authorized supplier, or the like.
Abstract:
An apparatus includes a three dimensional array of light receptors disposed within a substrate having a light receiving surface, where light receptors disposed closer to the light receiving surface are responsive to light having shorter wavelengths than light receptors disposed further from the light receiving surface, and where each light receptor is configured to output a binary value and to change state between an off-state and an on-state by the absorption of at least one photon.
Abstract:
A device for measuring calories of food items includes a food item holding unit on which an inspection-target food item including a plurality of food materials is placed, a light source for radiating near-infrared rays at a specific wavelength region to the food item, and a light reception unit that receives light emitted from the light source and then reflected from the food item. The light receiving device receives light reflected from the food item when the near-infrared rays at the specific wavelength are radiated to the food item. A control unit calculates calories of the food item in accordance with measurement values of absorbances of the near-infrared rays at the specific wavelength region which are received by the light reception unit.

Abstract:
A system for performing high-speed, high-resolution imaging cytometry includes a scanning region that is illuminated by light including at least first and second wavelength bands. The system also includes a cell transport mechanism that transports a cell through the scanning region such that the cell is illuminated. The system further includes a set of at least one linear light sensor, and an optical system that selectively directs light emitted from the cell to two portions of the linear light sensor set such that emitted light in a third wavelength band is primarily directed to a first portion of the linear light sensor set, and emitted light in a fourth wavelength band is primarily directed to a second portion of the linear light sensor set. The system repeatedly takes readings of light falling on the linear light sensor set while the cell is transported through the scanning region.
