摘要

#CMT# #/CMT# The device (1) has an infrared projector (2), a detector unit (5) and an evaluation unit. A radiation is generated by the infrared projector and is adjusted on road surface. The device receives radiations reflected in the detector unit and evaluated in the evaluation unit. A reflector (4) is assigned to the detector unit. The reflector reflects the radiation coming from the road surface and is focused in the direction of the detector unit. #CMT#USE : #/CMT# Device for determining condition of a road surface. #CMT#ADVANTAGE : #/CMT# The reflector reflects the radiation coming from the road surface and is focused in the direction of the detector unit, and thus enables to provide a simple device for reliable determination of road surface condition. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a condition determining device. 1 : Condition determining device 2 : Infrared projector 3 : Road surface 4 : Reflector 5 : Detector unit.
