LD Laser Scanners and Time of Flight

LD-OEM is a measurement scanner.  Using time of flight TOF SICK Laser Scanners are served for anti-collision for large harbor cranes, automatic parking of planes, vehicle classification in free-flow traffic, guidance and protection of autonomous vehicles, anti-intrusion in building security, people counting in crowded public areas.

Time of Flight technology principle:
SICK is the leader in Time of Flight (TOF) technology

LD laser scanner types of uses:


Paintings on a wall can be safeguarded by an invisible vertical barrier generated by a LD PDS Laser Scanner hidden in the ceiling. The scanner will detect any object penetrating the scanned area. In the same way, a horizontally mounted laser scanner can be used at night to prevent intrusions in gardens, on roofs, in rooms and any other areas.  Indoor or outdoor, the laser scanner will detect any person trespassing on your property and report it to you immediately.

SICK laser scanners are most commonly used for AGVs.

By using the LD NAV, the AGV can easily find its way by means of traditional triangulation on reflectors, when they are visible, and continue navigating by measuring the profile of the surrounding environment, when the reflectors become obscured.

The TOF capabilities of LD scanners have been exploited to provide accurate measurements of the shape of aeroplanes in order to guide them precisely to the docking area. The long-distance scanner LD Galileo is able to fulfill its measurement duties in bad weather conditions and on any target. Benefit from its constant accuracy and reliability.

LD scanners to guide Aeroplanes

The LD CS Cone Scanner is able to detect the exact position of the corners of a container and its relative position to the transport truck. The crane’s position is consequently automatically adjusted to pick or place the container. The system developed by SICK and LASE allows the automation of the containers’ handling by STS or Gantry Cranes and makes the operation at the quay-side much faster and safer.

LD devices are also used in harsh port environments for anticollision purposes between cranes and objects on the quays.
