Portable Instrument And Quick Charging Of Retroreflector Meter For Road Markings

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.

The retroreflective marking measuring instrument is a special optical measuring device used to measure the reflective performance of road markings. The measured parameter is the retroreflective coefficient R '(or specific brightness) of the marking, and the unit is mcd • lx -1 • m -2. The instrument is easy to operate and reliable in value. It can be used in laboratories as well as on-site measurement. It is the first-choice instrument for measuring the retroreflective optical performance of highway markings for production, quality supervision, engineering construction, supervision, teaching and scientific research.
