Laser scanning is the controlled deflection of laser beams, visible or invisible. [1] Scanned laser beams are used in some 3-D printers, in rapid prototyping, in machines for material processing, in laser engraving machines, in ophthalmological laser systems for the treatment of presbyopia, in confocal microscopy, in laser printers, in laser shows, in Laser TV, and in barcode scanners.
Quantapoint creates a Digital Facility [4] using 3D laser scanning and then provides visualization, analysis, quality control, decision support and documentation services [16] for buildings, museums, refineries, chemical plants, nuclear and fossil-fuel power plants, offshore platforms and other structures.
Laser scanning describes the general method to sample or scan a surface using laser technology. Several areas of application exist that mainly differ in the power of the lasers that are used, and in the results of the scanning process. Low laser power is used when the scanned surface doesn't have to be influenced, e.g. when it only has to be ...
VIEW Engineering's Logo, circa 1976 VIEW Engineering's Logo, circa 1996. While working as a physicist at Hughes Aircraft Company, Dick Hubach recognized a need for automated dimensional measurement systems, when he discovered that the cost to verify the correct manufacture of some aerospace components actually exceeded the cost to manufacture those components.

Scanning vibrometers – A scanning LDV adds a set of X-Y scanning mirrors, allowing the single laser beam to be moved across the surface of interest. Holographic laser Doppler vibrometry (HLDV) – An extended-illumination LDV that relies on digital holography for image rendering to capture the motion of a surface at many points simultaneously.
Confocal laser scanning microscopy and Two-photon excitation microscopy make use of lasers to obtain blur-free images of thick specimens at various depths. Laser capture microdissection use lasers to procure specific cell populations from a tissue section under microscopic visualization.
