Retroreflectometer For Road Markings
Product introduction
The geometric condition of STP-NRRM rainy night road marking
retroreflectometer is to simulate the brightness that the driver
observes in the cab reflected from the marking made of
retroreflective material on the road by the headlamp when the
vehicle is driven on the road at night.
The angle between the optical axis of the headlamp and the normal
line (reference axis) of the road surface is called the incidence
angle, which is set at 88.76° and the angle between the optical
axis of the headlamp and the reflected light is called the
observation angle, which is set at 1.05°. The light source of the
optical system is directed to the marking line according to the
incident angle. The size of measurement window is 450 x 65mm. The
reflected light from the marking line is received by the V(λ)
filter at the observation angle of 1.05°. After signal processing
and calculation, the measured value is displayed. This value is the
value of retroreflection coefficient RL.
