Working principle
Employing the principle of single-particle laser scattering, a precise optical design and an air path designed according to fluid dynamics principles ensure that particles in the sampled air pass through the laser beam with a high probability, generating weak scattered light. A precise optical signal collection device gathers this scattered light and projects it onto a highly sensitive, high-bandwidth, large-area photodetector. By identifying and analyzing the scattering pulse of each particle, the signal intensity corresponding to each particle is obtained; through a calibration procedure, the particle size of each particle is determined; and after conversion and aerodynamic calibration, the number of particles is obtained.
