Laser Scanning Predicts Soil Structure's Effect on Hydrology

Facebook X LinkedIn Email
The use of lasers to study soil hydrology (the movement of water through soil) may help soil scientists more accurately predict water flow. Researchers at the University of Kansas have used a multistripe laser triangulation (MLT) scanner, originally developed for engineering purposes, to quantify macropores in soil from an excavation wall in northeastern Kansas in order to determine how the pore size in soil may help predict the preferential flow of water. “A significant portion of water is transported through a relatively few number of large pores,” said professor...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    scanner
    1. A device used to trace out an object and build up an image. One of the most common of these types is video scanning. The scanning takes place inside the television tube as electrons, guided by electron optics, sweep linearly across a tube face coated on the inside with a phosphorescent material. A scanner can convert a paper drawing or photograph into pixels on a display screen. Scanners are also used to relay information in optical data processing. 2. A device that automatically measures or...
