Measuring Instruments and Data Processing for the Determination of Particle Size Distribution,1 mW He-Ne laser fitted with a spatial filter and a collimating lens which provides a parallel beam of monochromatic coherent light. The particles are placed in this beam and the scattered light is collected by a lens and brought to a focus on a special detector placed in the focal plane. The detect

Measurement of Particle Characteristics in Industry and Research,linders. At the same time the efficiency of the LP stages is only about 70%, in some cases even lower. Power losses arise as a result of the transportation and acceleration of the liquid drops, and also as a result of rotor braking caused by their impact on the blades. This impact is also a source o

Book 1981d together under the heading ‘scattering‘. Associated with the above there may be changes in frequency of the wave. This may arise due to the Doppler effect if the obstacle is moving or changing in time in any way. Also there can be changes in the energy of the object which must be matched by the wave, such as, for example, in the Raman effect.
