Method for evaluation of a scattered light signal and scattered light detector used for carrying out said method

The invention relates to the detection particularly particle housing above the supporting medium, detecting the diffused optical signal method for diffused light receiver comprises. So the diffused optical signal with the selection or circulates by any in continuously with calibration step and drift compensation and said temperature compensation step and sensitivity regulator step or the system further algorithm. The invention also relates for carrying out the upper method diffused light detector, comprising: aThe shell; and the inlet and outlet, between the inlet and outlet the supporting medium wound by the shell and oil groove; Direction and printing light diffused centre light source is flow channel; For receiving the diffused light outlet face to particle on the light the diffused light receivers; And the diffused optical signal for amplifying the diffused signal light.
