Abstract: In an optical measurement method, light is directed from a light generator to a light path cell. A light path is generated by continuously reflecting the light between first and second high reflection mirrors within a light path cell that face to each other. An optical signal is detected from an aerosol sample present within a range of the light path. The optical signal is separated into a particle signal and a gas signal by using a statistical methodology. A particle concentration is calculated from the particle signal by using an assumption of an optical particle counter (OPC). A gas concentration is calculated from the gas signal by using optical characteristic data of gas.

Abstract: An optical measurement method includes emitting light to an optical beam path cell including a first mirror and a second mirror that faces the first mirror, forming an optical beam path by reflecting the light between the first mirror and the second mirror, obtaining an optical signal including an optical characteristic value based on an interaction of the light with a sample in the optical beam path, separating the optical signal into a gas signal and a particle signal, and determining a concentration of particles in the sample based on the particle signal, where the determining of the concentration of the particles includes fitting the particle signal into a first distribution function indicating the optical characteristic value and a frequency of the optical characteristic value, and the concentration of particles is determined based o999n first shape information about the first distribution function.
