Abstract
A particle-measuring system for determining particle mass concentrations in aerosols has a laser diode serving as a radiation source and projecting a beam of laser light through a flowing stream of the aerosol. A receiver for receiving the light from the diode after passing through the stream and converting the received light into a measurement. A frequency radiation output of the laser diode is modulated such that the frequency is substantially greater than a cutoff frequency of the receiver so that a specifiable radiation output of the laser diode is achieved on average over a duration of a measurement signal of the receiver.
