Class Information
Number: 356/337
Name: Optics: measuring and testing > By particle light scattering
Description: Subject matter to visually or photoelectrically inspect or measure the atmospheric scattering of light, or the scattering by molecules of a gas or liquid media or by particles entrained in a flowing or static medium, which includes support means for the media or medium capable of transmitting light into and out of the support means, lighting means to direct light into and through a flowing or static gas or liquid with or without the entrained particles, and means to visually examine and measure or photoelectrically detect and indicate the intensity of the light scattered from the medium or from the particles in the medium at some angle other than the direction of the inspection light.
