Abstract: Provided are a fire detection apparatus and method for analyzing a spectral distribution of secondary light generated as primary light is scattered or transmitted through smoke particles to distinguish between fire smoke generated due to an actual fire and living smoke generated in daily life, thereby reducing non-fire alarms. When smoke enters the inside of the fire detection apparatus (100) due to a fire, secondary light (150) scattered or transmitted through smoke particles (140) is incident on the light receiver (120). Upon receiving the secondary light (150), the light receiver (120) outputs a spectrum (170) of the secondary light (150). The fire identification unit (160) receives and analyzes the spectrum (170) of the secondary light (150) and identifies whether the smoke particles (140) are particles of living smoke or particles of fire smoke.

Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.

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.
