Remote detecting apparatus and method for air pollution using differential optical abosrption spectroscopy

摘要

PURPOSE: A remote measuring device for air pollution materials using differential optical absorption spectroscopy and a method thereof are provided to enable accurate alignment of light, emitted from a transmitting optics, on one spot in the air using a light path alignment unit. CONSTITUTION: A remote measuring device for air pollution materials using differential optical absorption spectroscopy comprises a main body and a light path alignment unit(100). The main body comprises a transmitting optics(80) and a receiving optics(90). The transmitting optics irradiates the light on one spot in the air. The receiving optics receives the light reflected by a reflector(110). The light path alignment unit emits laser on the spot. The light path alignment unit aligns the light path, emitted from the transmitting optics, to the spot.
