  • Monitor for environmental particulate matter size, concentration, and complex index of refraction
    Patent number: 11733149
    Abstract: Apparatus and methods for determining particle size, and optionally, the complex index of refraction for particle suspended in a gas or liquid are provided. The particle to be analyzed is caused to travel through a laser beam having a modified Gaussian profile. The particle causes light from the laser beam to scatter. The scattered light is measured by one or more photodetectors disposed at a particular scattering angle relative to the center of the laser beam. The apparatus and methods can be used in sensors configured to monitor air quality in enclosed environments, such as on-board aircraft and within buildings, and/or detect environmental contaminants.
