PRINCETON, N.J., Aug. 19, 2008 -- A new approach that combines a laptop computer, flatbed scanner, and a turntable with a laser rangefinder automates a painfully slow task facing archaeologists -- reconstructing ancient artifacts from thousands of tiny, often-eroded pieces. For several decades, archaeologists in Greece have been attempting the Herculean task of reconstructing wall paintings that hold valuable clues to the ancient culture of Thera, an island civilization that was buried under volcanic ash more than 3500 years ago. At their current rate, it will take more than a century to complete their fresco fragment...Read full article

    laser rangefinder
    A laser rangefinder is a device that uses laser technology to measure the distance between the device and a target. It operates on the principle of measuring the time it takes for a laser beam to travel to the target and back, calculating the distance based on the speed of light. Laser rangefinders are commonly used in various applications, including surveying, hunting, golfing, military and defense, and outdoor activities. Key points about laser rangefinders: Distance measurement: The...
    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...
