Title:
SENSOR DEVICE FOR DETECTING BIOLOGICAL PARTICLES AND NON-BIOLOGICAL PARTICLES
Document Type and Number:
WIPO Patent Application WO/2023/048406
Kind Code:
A1
Abstract:
Various embodiments of the present invention relate to a sensor device comprising a second light-condensing mirror unit having a plurality of spherical mirrors formed to reduce the thickness of a light-condensing mirror unit. According to one embodiment, a sensor device for detecting biological particles and non-biological particles may comprise: at least one light-source unit for radiating ultraviolet rays; and a light-condensing mirror unit including a first light-condensing mirror unit disposed in front of the at least one light source unit and a second condensing mirror unit spaced apart from the first light-condensing mirror unit, wherein: the light-condensing mirror unit reflects a fluorescence signal of biological particles in the air and a scattering signal of non-biological particles in the air, the fluorescence signal and the scattering signal being generated in an air passage by radiation of the ultraviolet rays passing between the first light-condensing mirror unit and the second light-condensing mirror unit; and the second light-condensing mirror unit has a plurality of spherical mirrors to reduce the thickness of the light-condensing mirror unit. In addition, various other embodiments are possible.
