| titleOfInvention | Laser sensor for ultrafine particle size detection |
| abstract | The present invention describes a laser sensor module for detecting ultrafine particles having a particle size of 300 nm or less, more preferably 200 nm or less, most preferably 100 nm or less. The laser sensor module comprises: at least one laser adapted to emit laser light in at least one focal area in response to a signal provided by at least one electric driver; At least one detector adapted to determine a self-mixing interference signal of light waves in a laser cavity, said self-mixing interference signal being caused by reflected laser light re-entering said laser cavity The reflected laser light is reflected by particles receiving at least a portion of the laser light, and the laser sensor module performs at least one self-mixing interferometric measurement The laser sensor module is configured to The laser sensor module is adapted to determine a first particle size distribution function with a first sensitivity according to at least one measurement result determined based on one self-mixing interference measurement, the laser sensor module comprising Further adapted to determine a second particle size distribution function with a second sensitivity different from the one sensitivity, wherein the at least one evaluator is configured to determine a calibration factor q in the second particle size distribution function It is adapted to determine a particle measure of particle size below 300 nm by subtracting the multiplied from said first particle size distribution function. The invention further describes corresponding methods and computer program products. The present invention enables a simple, low cost particle detection module or flush water detector based on laser self-mixing interference that can detect particles with a size of 100 nm or even smaller. |
