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.

Provided are an apparatus and method for adjusting an optical axis. In the apparatus, an iris diaphragm and a quadrant photodiode (QPD) are used to align optical axes of an optical system of the apparatus so that optical transmission efficiency between an optical transmitter and an optical receiver can be increased. Since a hole of the iris diaphragm can be adjusted to be small, a beam larger than a light-receiving area of the QPD can be included in the light-receiving area, and optical axis alignment is facilitated accordingly. When the QPD and the iris diaphragm are applied to the apparatus, it is possible to simultaneously perform data transmission, tracking, and optical axis alignment. An optical fiber end surface and optical axes of lenses arranged in parallel are aligned in the apparatus so that alignment between two terminals can be easy and reception efficiency can be increased.
