Pollen discrimination and count, by "Degree of Polarization" This sensor detects the particle with light scattering method, using one light emitter and two light receptors, and discriminates pollen from other particles with two factors "scattered light intensity" and "degree of polarization".
· We demonstrate a high throughput, allelectronic Coultertype sensor with four sensing microapertures to detect and count microscale particles. Four particle samples are utilized for this study: polymethacrylate particles 40 µm and 20 µm in diameter, Juniper Scopulorum (Rocky Mountain Juniper) pollen and Cottonwood pollen particles. The two types of pollen particles are roughly 20 µm in ...

Bei Wetter interessieren nicht nur Temperatur und Regenwahrscheinlichkeit – auch der Pollenflug ist für Allergiker eine wichtige Information. Um diesen besser zu vorhersagen, haben Forscher der TU Graz einen Prototyp entwickelt, mit dem sich Pollen …
· The use of libraries calibrated with dried pollen is however very limited for an operational pollen monitoring due to the morphological differences between fresh and dried pollen. We expect that best results can be obtained with samples inserted into the detector shortly after collection (within few hours). A systematic collection of fresh pollen samples is in this line planned for the next ...

Besides, a separate set of 135 videos (containing 1234 pollen grains of 11 pollen types) was used to evaluate detection performance. The results are promising in detection (% of recall and % of precision) and location accuracy ( IoU as the average value). These results suggest that this technique can provide a reliable basis for the development of an automated pollen counting system.
"Pollinosis" or Seasonal Allergic Rhinitis occurs during specific seasonal periods when plants shed pollen. Our sensor can distinguish between Japanese cedar or cypress pollen and dust by comparing scattered light and degree of polarization.
