  2. Laser projector - Wikipedia

    en.wikipedia.org/wiki/Laser_projector

    In the case of using a computer to control a laser projector, a digital-to-analog converter (DAC) is needed to convert the digital control signal from the computer into analog signals that control the scanners in the laser projector. Typically, two channels are used for x-y position control and three channels are used for controlling the RGB ...

  3. Laser scanning - Wikipedia

    en.wikipedia.org/wiki/Laser_scanning

    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.

  4. Galvanometer - Wikipedia

    en.wikipedia.org/wiki/Galvanometer

    An early D'Arsonval galvanometer showing magnet and rotating coil. A galvanometer is an electromechanical measuring instrument for electric current.Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely.

  5. Mirror galvanometer - Wikipedia

    en.wikipedia.org/wiki/Mirror_galvanometer

    Late 19th or early 20th century. This galvanometer was used at the transatlantic cable station, Halifax, NS, Canada Modern mirror galvanometer from Scanlab. A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless ...

  8. Thermo galvanometer - Wikipedia

    en.wikipedia.org/wiki/Thermo_galvanometer

    The thermo-galvanometer designed by Mr W. Duddell can be used for the measurement of extremely small currents to a high degree of accuracy. It has practically no self-induction or capacity and can therefore be used on a circuit of any frequency (even up to 120,000~ per sec.) and currents as small as twenty micro-amperes can be readily measured ...
