Abstract:
An optical analysis device for determining particulate matter includes three light sources having different wavelengths, an apparatus for combining the three transmitted light beams on a common optical path, a measurement volume, an optical axis in the forward scattering direction defines the scattering angle 0°, a light absorption apparatus at 0° that absorbs unscattered light, and six detectors which are arranged at different specified angles which are as close as possible to 0° directly next to the light absorption apparatus, at a second scattering angle between 7° and 40°, at a third scattering angle between 41° and 70°, at a fourth scattering angle between 71° and 115°, at a fifth scattering angle between 116° and 145°, at a sixth scattering angle between 146° and 180°. A control and evaluation unit controls the light sources such that the scattered light is detected in a wavelength selective manner by the detectors.

Claim (Index 1):
An optical analysis device ( 10 ) for determining particulate matter, said optical analysis device ( 10 ) comprising\n three light sources (L 1 , L 2 , L 3 ) for transmitting three transmitted light beams (S 1 , S 2 , S 3 ) having different wavelengths; an apparatus ( 22 ) for combining the three transmitted light beams (S 1 , S 2 , S 3 ) on a common optical path ( 24 ); a measurement volume ( 25 ) into which gas charged with particulate matter can be introduced and in which the transmitted light (S 1 , S 2 , S 3 ) is incident on the gas to be measured and is scattered at the particulate matter and a center ( 29 ) is defined in the measurement volume from where scattering angles (\u03b1) are defined, with the optical axis in the forward scattering direction defining the scattering angle 0\u00b0; a light absorption apparatus ( 30 ) at 0\u00b0 that detects unscattered light; a first detector ( 40 ) that is arranged as close as possible to 0\u00b0 directly next to the light absorption apparatus ( 30 ) and that detects scattered light in the forward direction; a second detector ( 42 ) that is arranged at a second scattering angle between 7\u00b0 and 40\u00b0; a third detector ( 44 ) that is arranged at a third scattering angle between 41\u00b0 and 70\u00b0; a fourth detector ( 46 ) that is arranged at a fourth scattering angle between 71\u00b0 and 115\u00b0; a fifth detector ( 48 ) that is arranged at a fifth scattering angle between 116\u00b0 and 145\u00b0; a sixth detector ( 50 ) that is arranged at a sixth scattering angle between 146\u00b0 and 180\u00b0 so that the detectors detect scattered light at the respective angle; a control and evaluation unit ( 60 ) that controls the light sources (L 1 , L 2 , L 3 ) such that the scattered light is detected in a wavelength selective manner by the detectors ( 40 ,  42 ,  44 ,  46 ,  48 ,  50 ); a memory ( 62 ) for storing the detected scattered light intensities; and the control and evaluation unit ( 60 ) is configured such that the size distribution of the particular matter and the particular matter mass percentages can be determined from the scattered light intensities.
