What is the difference between a laser displacement sensor and a laser ranging sensor?

When many customers choose laser sensors, they do not know the difference between displacement sensor and ranging sensor. Today we will introduce them to you.

The difference between a laser displacement sensor and a laser ranging sensor lies in the different measurement principles.

Laser displacement sensors are based on the principle of laser triangulation. The laser displacement sensor can realize non-contact long-distance measurement by utilizing the characteristics of high directivity, high monochromaticity, and high brightness of the laser.

Laser ranging sensors emit a very fine laser beam at the target based on the time of flight of the laser. The laser beam reflected by the target is received by the optoelectronic element. The distance between the observer and the target is calculated by measuring the time from emission to reception of the laser beam with a timer.

Another difference is the different application areas.

Displacement sensor lasers are mainly used to measure the displacement, flatness, thickness, vibration, distance, diameter, etc. of objects. Laser ranging sensors are mainly used for traffic flow monitoring, illegal pedestrian monitoring, laser ranging, and obstacle avoidance in new fields such as drones, and autonomous driving.

Seakeda focuses on the research and development and production of laser distance sensors. Our laser sensors have millimeter-level precision detection and low false alarm rate; they have different ranges such as 10 meters, 20 meters, 40 meters, 60 meters, 100 meters, 150 meters, and 1000 meters. , wide measurement range, stable performance, long service life; using phase, pulse and time-of-flight measurement principles; IP54 and IP67 protection grades adapt to different indoor and outdoor working environments, and maintain high measurement accuracy and reliability; more A variety of industrial interfaces to meet the integration of different equipment systems. Support connection with Arduino, Raspberry Pi, UDOO, MCU, PLC, etc. to transmit data.
