Contact-less on-line measurement and/or on-line detection method for e.g. conjugated organic compound on roadway surface, involves detecting reflected light from surface, and comparing and evaluating signals by signal evaluation system

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and system for detecting and measuring specific substances, such as conjugated organic compounds, on road surfaces without any physical contact. It uses pulsed ultraviolet (UV) light to illuminate the roadway, then detects and analyzes the reflected light to determine the presence of these compounds. The analysis is carried out in real-time using a signal evaluation system that interprets color and brightness changes.

Patent Abstract

The method involves illuminating a roadway surface (2) by a light source with pulsed UV light (4). Reflected light (5) from the roadway surface is detected in adjustment with the frequency of the light source by a light receiver when illuminating with the UV light and/or without the illumination with the UV light. The signals of the light receiver are compared and evaluated by a color and/or brightness signal evaluation system. The roadway surface is illuminated with the light of wavelength of 230 nanometers to 400 nanometers. An independent claim is also included for a system for contact-less on-line measurement and/or on-line detection of conjugated organic compounds on a roadway surface.
