    Abstract: Disclosed herein are a diagnostic method using laser induced breakdown spectrum analysis and a diagnostic device for performing the same. The diagnostic method may include projecting a pulsed laser to a suspicious specimen, obtaining first spectrum data on the light collected from the suspicious specimen, projecting the pulsed laser to a non-diseased specimen, obtaining second spectrum data on the light collected from the non-diseased specimen, and determining whether a disease is present in the suspicious specimen from a comparison value of the first spectrum data and the second spectrum data using an artificial neural network.

    Abstract: A calibrator of an OES may include a cover, a reference light source and a controller. The cover may be detachably combined with a ceiling of a plasma chamber of a plasma processing apparatus. The reference light source may be installed at the cover to irradiate a reference light to the OES through an inner space of the plasma chamber. The controller may compare a spectrum of the reference light inputted into the OES with a spectrum of an actual light inputted into the OES during a plasma process in the plasma chamber to calibrate the OES. Thus, the OES may be calibrated without disassembling of the OES from the plasma chamber to decrease a time for calibrating the OES.

    Abstract: A system and method for non-destructive, in situ, positive material identification of a pipe selects a plurality of test areas that are separated axially and circumferentially from one another and then polishes a portion of each test area. Within each polished area, a non-destructive test device is used to collect mechanical property data and another non-destructive test device is used to collect chemical property data. An overall mean for the mechanical property data, and for the chemical property data, is calculated using at least two data collection runs. The means are compared to a known material standard to determine, at a high level of confidence, ultimate yield strength and ultimate tensile strength within +/−10%, a carbon percentage within +/−25%, and a manganese percentage within +/−20% of a known material standard.

    Abstract: The present invention relates to an optical analysis device using a multi-light source structure, which allows acquisition of an optimized measurement result by adjusting the number of light sources depending on a concentration of an object to be measured, such as ocean spilled oil, etc., and a method therefor. The optical analysis device using a multi-light source structure may comprise: a multi-light source unit including multiple light source units each having a light source which is selectively illuminated, in order to adjust an amount of light depending on a concentration of an object to be measured; a cuvette unit including a cuvette in which an object to be measured is disposed, wherein the cuvette has a prism shape and has as many faces as the number of the light source units plus one, the light source units faces the faces, respectively, and reactive light generated from the object to be measured is emitted through the remaining one face; a light sensor unit for detecting the reactive light emitted through the cuvette; and a control unit for controlling illumination of the light source units configuring the multi-light source unit.
