Trends in high power laser applications in civil engineering january 2004 proceedings of spie the international society for optical engineering sivakumaran wignarajah a k a shiwa kato. Laser checking is an earthly laser imaging. To help understand the way the instrument is used a description of the basic system operation is given followed by a detailed explanation of the main instrument features.

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. 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.
