Abstract: An apparatus and method for detecting smoke using multi-angle light scattering. The apparatus includes a light source array in which a plurality of light sources outputting optical signals of a same wavelength are arranged at a regular interval and configured to output the optical signals at different irradiation angles to smoke particles, a lens configured to divert optical paths of the optical signals output from each of the plurality of light sources included in the light source array, an optical detector configured to measure the optical signals that pass through the lens and are scattered and absorbed by the smoke particles, and a computing device configured to classify types of the smoke particles using a scattering coefficient and an absorption coefficient of the smoke particles determined through the measured optical signals.

Abstract: Provided are a multiwavelength photoelectric smoke detection apparatus and method, which reduce non-fire alerts by distinguishing smoke caused by actual fire occurrence and non-fire smoke occurring in daily life when a suspected fire event occurs. The multiwavelength photoelectric smoke detection apparatus includes a chamber in which a smoke inlet is formed, a light emitter for generating light with multiple wavelengths, a light receiver for detecting scattered light due to smoke particles, a controller for turning a light source of the light emitter on and off and detecting a scattered light signal from the light receiver, and a fire determination part for determining whether an amplitude of the detected scattered light signal exceeds a threshold value and generating an alarm.

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.
