Optical biofilm sensor for determining biological properties of biofilm on settlement substrate, has set of photoconductive glass fibers arranged under substrate and around light source, where light source is arranged in sensor head

摘要

The sensor has a defined emission spectrum radiating light source (1) arranged in a sensor head (2). A detector detects light emitted from a biofilm (3). A set of photoconductive glass fibers (5) is arranged under a settlement substrate (4) and around the central light source, where the light source is arranged in the sensor head. The glass fibers are arranged in a set of concentric circles, and are pivotable around a spatial axis in an angle of incidence (6). The biofilm is rearwardly irradiated by the light source. The light source is selected from an LED, a laser diode or a UV lamp.
