The term laser is an acronym for light amplification by stimulated emission of radiation. The laser based system can measure the road profile and deflection accurately while traveling at an average speed. Pavement deflection measurement at traffic speed.

A laser is an optical device that emits coherent light electromagnetic radiation. Application of lasers in highway engineering laser based road profile measuring system are non contact type system capable of measuring road profile and road deflection at normal traffic speeds. Laser mapping for highway engineering surveys. Application of lasers in highway engineering laser based road profile measuring system are non contact type system capable of measuring road profile and road deflection at normal traffic speeds.

It doesn t require any setup or break down. Show full abstract metals and plastics are used in very large quantities for civil engineering construction. Multiple locations can be measured from a single instrument position. Typically lasers are thought of as emitting light in a narrow low divergence beam with a narrow wavelength spectrum monochromatic light.
