Laser Scanners

Laser scanners function according to the principle of the pulse time-of-flight measurement. An invisible laser beam pulse is emitted in a fan shape with a high angular velocity as a measurement probe. If this hits an object, it is reflected and this is registered in the laser scanner’s receiver. The time take for the pulse to be sent and received again (light time-of-flight) is directly proportional to the distance between scanner and object. The exact position of the object is calculated from the sequence of pulses received. Violations of the monitoring areas are reported immediately through an output signal switching device.

Laser scanners are commonly used in security, transportation and industrial applications such as:
