Sensor for measuring the air quality, a mobile telecommunication terminal with a sensor for measuring the air quality and process for the measurement of the air quality with a mobile telecommunication terminal

摘要

It is a sensor for measuring the air quality is proposed with a beam source for generating a primary beam, a beam shaping means for manipulating, in particular focusing, of the primary beam and a beam detector for detecting a from the primary beam by reflection on particles resulting secondary beam, wherein the beam source itself is a laser emitter of interfering.n="36"
