WebIntroduction. Particle measurements using optical instruments are based on the fact that when a particle passes through a beam of light, some of the light is scattered. Detection of this scattered light is the basis of all such instruments. Particle number can be determined simply by counting the pulses of scattered light reaching the detector. WebRayleigh's method requires an assumed displacement function. The method thus reduces the dynamic system to a single-degree-of-freedom system. Furthermore, the assumed displacement function introduces additional constraints which increase the stiffness of the system. Thus, Rayleigh's method yields an upper limit of the true fundamental frequency.

The intensity of scattered light depends on the size of the particles and the wavelength of the light. Shorter wavelength and high-frequency scatter more due to the waviness of the line and its intersection with a particle. The wavier the line, the more the chance it intersects with a particle. share a similar internal bone structure

WebRayleigh Scattering If the particles are small compared to the wavelength of the laser used (typically less than d ª 10 or around 60nm for a He-Ne laser), then the scattering from a particle illuminated by a vertically polarised laser will be essentially isotropic, i.e. equal in all directions.
