A surface plasmon resonance imaging apparatus is provided. The surface plasmon resonance imaging apparatus includes a light irradiation unit configured to irradiate polarized light onto a metal coating film provided on one surface of a prism, a light modulator configured to spatially pattern-encode light reflected by the metal coating film and the prism, a light detector configured to detect a pattern-encoded light signal, obtained through pattern-encoding by the light modulator, as a spectral signal, a signal processor configured to spatially decode the spectral signal and analyze a decoded spectral signal to generate characteristic data of a sample provided on the metal coating film, and an output unit configured to output the characteristic data of the sample as a two-dimensional (2D) image.
Abstract:
A fire detection method is provided. The fire detection method calculates a singular value for determining whether smoke penetrating into a chamber is caused by a fire or a non-fire by using the processor, based on n number of normalized values of scattered light and n number of normalized values of transmitted light.
Abstract:
A lighting fault diagnosis method includes determining a fault item among a plurality of fault items based on fault symptom data of a test for each fault item, and recommending a repair method suitable for the determined fault item.
Abstract:
The disclosure relates to a non-dispersive infrared (NDIR) gas sensor which detects the concentration of gas with a simple structure and method by manufacturing an optical waveguide with a gas-permeable polymer material instead of a conventional cavity or chamber type. An optical signal travels through the optical waveguide of gas-permeable polymer by total internal reflection, and the gas naturally penetrates the optical waveguide without the use of separate inlet and outlet openings, so that the optical signal and gas particles come into contact with each other within the optical waveguide. Since the optical signal detected by a photodetector at the other end of the optical waveguide after traveling while contacting the gas particles has properties changed according to the concentration of the gas which they have contacted in the optical waveguide, it is possible to measure the concentration of a specific gas from the detected optical signal.

Abstract:
An apparatus and method for abnormal situation detection are disclosed. An abnormal situation detection apparatus can map first sensor data among sensor data transmitted from a plurality of sensors into a vector value, convert it into first situation information in the form of an image pattern, and generate a learning model using the first situation information and an abnormal situation reference range. In addition, the abnormal situation detection apparatus can convert second sensor data among sensor data transmitted from a plurality of sensors into a form that can be input to the learning model, and determine whether an abnormal situation occurs by applying the converted second data to the learning model.
