Atmospheric ultrafine particulate matter moisture absorption growth detection device based on surface wave imaging

Abstract

The invention discloses an atmospheric ultrafine particulate matter moisture absorption growth detection device based on surface wave imaging. According to the device, a measurement cavity is arranged on a surface wave imaging substrate; an oil immersion microscopic objective, a microscopic imaging assembly, a polarization filter and an imaging detector are sequentially arranged below the surface wave imaging substrate; the oil immersion microscopic objective is arranged at the front end of the microscopic imaging assembly; a surface wave excitation assembly is arranged on the side face of the microscopic imaging assembly, and emergent light of the surface wave excitation assembly sequentially passes through the microscopic imaging assembly, the oil immersion microscopic objective and the surface wave imaging substrate to reach the measurement cavity, and then the light sequentially reaches the surface wave imaging substrate, the oil immersion microscopic objective, the microscopic imaging assembly and the polarization filter from the measurement cavity, and then reaches the imaging detector to form a detection light path. The device is high in imaging sensitivity, can realize real-time dynamic monitoring on a single superfine atmospheric particulate matter, can work in a real atmospheric environment, and is high in reliability, and the surface wave imaging substrate of the detection device can be repeatedly used.

AI Technical Summary

Benefits of technology

The present technology relating to detecting small air pollution from gaseous emissions has several technical benefits: It uses specialized equipment called Surface Wave Imaging (SWI) devices to capture images on surfaces without being affected by external factors such as temperature variations; this allows for precise measurements over time while maintaining their effectiveness at different temperatures and environments. This makes them highly reliable even when used repeatedly during operation under varying conditions like weather patterns.

Problems solved by technology

This patents describes different methods used by scientists studying tiny particles called UF (ultraviolet rays). These small particles absorb water vapor when exposed to sunlight without losing their shape over long periods. However, these techniques require specialized equipment and trained operators who may lack knowledge about how this happens. Additionally, current studies show poor temporal resolution and limited ability to monitor individual particles individually.
