How reflectance affect the laser scanner range measurement?
5 answers
Reflectance significantly impacts laser scanner range measurements. High reflectivity surfaces, like mirrors, glass, or highly reflective materials, can cause errors in distance data due to specular reflections, leading to phantom-like objects and wrong distance measurements. Specular reflections from such surfaces can increase laser signal power, causing disorder in echo detection and recognition, resulting in significant errors in distance observations. Studies suggest that the reflectance of the calibrator used for calibration plays a crucial role in measurement accuracy, with optimal results obtained when using calibrators with specific reflectance levels around 18%. Reflectivity variations can lead to systematic deviations in reflectorless electronic distance measurements, with diffusely reflecting surfaces causing deviations of a few millimeters and directionally reflecting surfaces causing even more significant errors.

HOW DOES CaO IN STEEL PRODUCTION CAN POLLUTE THE SOIL?
4 answers
CaO in steel production can lead to soil pollution through the disposal of steel slag, a byproduct rich in CaO, onto land. Steel slag, containing CaO along with other components, is often not efficiently utilized, resulting in large stockpiles that can occupy vast areas and cause environmental issues like groundwater and soil pollution. Additionally, the steel industry's operations generate solid wastes that can impact soil quality. The presence of CaO in steel slag, when not properly managed, can contribute to heavy metal contamination in soil. Improper disposal of steel industry waste, including CaO-rich slag, can result in the release of heavy metals like Cd, Cr, Cu, and Pb into the soil, leading to contamination and necessitating soil treatment measures.
