10.10 Applications of lasers Lasers find applications in various fields of science and technology. In this Era of technology, Lasers have a very vast application in Highway Engineering. They are described below: (1) In communications: Lasers are used in optical fibre communicatiuons. It eliminates the need for lane closures or traffic control while testing. If compared to older techniques that were cumbersome, these have higher accuracy since everything is … 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. They are described below:O’Reilly members experience live online training, plus books, videos, and digital content from Take O’Reilly online learning with you and learn anywhere, anytime on your phone or tablet. Laser based system can measure road profile and deflection accurately while travelling at normal speed. In this Era of technology, Lasers have a very vast application in Highway Engineering.These techniques have eased Human work by making it simple and easy to use. 2.

If compared to older techniques that were cumbersome, these have higher accuracy since everything is automated and quicker in obtaining results since its computed by a computer and need very less human power. The specific instrument discussed is a laser-based instrument that has been successfully used in a number of applications related to highway bridges.

O’Reilly members experience live online training, plus books, videos, and digital content from Lasers find applications in various fields of science and technology. It results in rapid measurement and quick data collection. 3D Laser Scanning is used in numerous applications: industrial, architectural, civil surveying, urban topography, mining, reverse engineering, quality, archaeology, dentistry, reverse engineering, and mechanical dimensional inspection are just a few of the versatile applications. The energy of a narrow laser beam is highly concentrated at 10 8-10 10 W/cm 2, so a weak weld pool is formed very rapidly (for about 10-6 sec). For testing strength of the construction or old conconstructions to re build or dismantled. Part one gives an overview of the use of lasers in medicine, key principles of lasers and radiation interactions with tissue. Lasers for Medical Applications summarises the wealth of recent research on the principles, technologies and application of lasers in diagnostics, therapy and surgery. Pavement deflection measurement at traffic speed. The laser beam heats and melts the edges of the workpiece, forming a joint.

In optical … - Selection from Engineering Physics [Book] It collects data in real-time as it traverses the pavement’s surface.

These techniques have eased Human work by making it simple and easy to use. 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 single instrument position. It is rare but laser was used to for various test in civil engineering department such as 1.
