Explication laser
WebIncident laser light is scattered or diffracted by particles. The diffraction angle depends on the particle size. Large particle scatter light to smaller angles, whereas smaller particles scatter light to larger angles. By analyzing an angle-dependent scattered light pattern, the particle size distribution can be calculated. WebOpt. Le laser consiste en un milieu amplificateur placé dans une cavité résonante qui fournit un rayonnement d'ondes cohérentes et monochromatiques par émission …
