A structured-light 3D scanner is a 3D scanning device for measuring the three-dimensional shape of an object using projected light patterns and a camera system. [ 1] The light source from the scanner head projects a series of parallel patterns onto the scan target. When light projects onto the object's surface, the patterns become distorted.
Lidar ( / ˈlaɪdɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [ 1] or "laser imaging, detection, and ranging" [ 2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Photoelectric sensor. Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.
A radar detectoris an electronic device used by motoriststo detect if their speed is being monitored by policeor law enforcementusing a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. In general sense, only emitting technologies, like doppler RADAR, or LIDARcan be detected.
Photodetectors may be used in different configurations. Single sensors may detect overall light levels. A 1-D array of photodetectors, as in a spectrophotometer or a Line scanner, may be used to measure the distribution of light along a line. A 2-D array of photodetectors may be used as an image sensor to form images from the pattern of light ...
An image scanner —often abbreviated to just scanner —is a device that optically scans images, printed text, handwriting or an object and converts it to a digital image. Commonly used in offices are variations of the desktop flatbed scanner where the document is placed on a glass window for scanning.
On-board diagnostics. Various views of a "MaxScan OE509" – a fairly typical onboard diagnostics (OBD) scanner, 2015. On-board diagnostics ( OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this capability is a requirement to comply with federal emissions standards to detect failures that ...
