3D digital devices that work by projecting laser light onto surfaces, while cameras triangulate the the profile of the laser as it sweeps along, enabling the object to be digitized in 3D
An optical barcode reading device using a low energy laser light beam as its source of illumination. More info here.
An optical bar code scanning device using a low-energy laser as its source of light. Laser scanners have the best read rate of all types of scanners.
Scanner using laser beams to record images on film.
A laser beam passed through each pixel of a radiograph or picture to measure the amount of transmitted light. This requires a conventional radiograph and is limited by the small dynamic range of radiographic film.
An optical bar code reading device that uses a low energy laser light beam to examine a spatial pattern, one part after another. It then generates analog or digital signals corresponding to the pattern. Laser scanners are often used in mark sensing, pattern recognition, character recognition, and bar code recognition. The laser scanner converts bar code symbols to electrical signals for input to a bar code reader decoder for processing and subsequent output through a data communications interface.
