In road engineering, it is most commonly used to evaluate: How a Retroreflectometer Works Although designs vary, most modern retroreflectometers operate using the following principle: 1. Controlled Light Source The device emits a beam of light at a defined angle toward the surface being tested. 2. Measurement of Reflected Light Sensors capture the amount of light that returns toward the source. 3. Calculation of RL Value The instrument calculates luminance ...\" \/>\n<meta property=\"og:url\" content=\"https:\/\/roadskymarking.com\/it\/retroreflectometer-what-it-is-how-it-works-types-uses.html\/\" \/>\n<meta property=\"og:site_name\" content=\"Nanjing Roadsky Traffic Facility Co.,Ltd.
