Abstract: 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: 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: 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.
