A Laser Displacement Sensor is a device that uses laser technology to measure the distance between the sensor and an object. It emits a laser beam that reflects off the surface of the target, and the sensor calculates the distance based on the time it takes for the light to return. This technology allows for precise measurements, often within micrometers. These sensors are widely used in various industries, including manufacturing and robotics, for applications such as quality control, automation, and material thickness measurement. Their non-contact nature makes them ideal for measuring delicate or moving objects without causing any damage.
