SYSTEM AND METHOD FOR DETECTING FINE DUST USING LOW-POWER LASER

摘要

The present invention relates to a system and method for detecting low-power laser fine dust, and in particular, horizontally irradiating three low-power laser beams from a laser generator on one side of a body with an open top and a translucent cell at the bottom, and irradiating three low-power laser beams to the opposite end surface. Receives laser light from the light receiving unit, receives a detection signal from the light receiving unit, separates fine dust particles that accumulate on the upper part of the translucent cell according to their size, and receives an absorption intensity signal that changes according to the distribution of fine dust particles. A low-power laser fine dust detection system and method for analyzing the movement speed, shape, distribution, size and amount of fine dust particles based on this.
