1mm Accuracy 20m Laser Distance Sensor

This Laser Range Module is characterized by its compact and lightweight design, capable of accurately measuring distances of up to 10 meters in a quick and efficient manner. The Precision Laser Distance Sensor's engineering ensures a smaller and lighter form factor, improved energy efficiency, and a competitive cost without compromising performance. The Phase Distance Sensor is compact in size with a width of 15mm, a length of 42mm and a thickness of 6mm. In addition, the laser range module can accurately measure distance with an accuracy of 1mm. The distance measurement method used in this laser range module is phase laser ranging. The LDL Laser Ranging Sensor utilizes phase laser ranging for measurement.

Phase laser ranging is generally well suited for measuring short and medium range distances. The Laser Sensor provides measurements accurate to the millimeter level and is one of the most accurate distance measurement methods available. Many short-range ranging applications use this method. In phase ranging, the intensity of the emitted light wave is modulated by the signal, and time is measured indirectly by observing the phase difference. This method of High Precision Laser Distance Sensor is easier to handle than directly measuring round trip time.

 Phase laser ranging involves utilizing the radio band frequency for amplitude modulation of the laser beam, followed by measuring the phase delay generated by the round-trip of the modulated light. This allows for conversion of the phase delay to represent distance based on the wavelength of the modulation light. The time for light to travel through the round trip measurement line is indirectly measured. Precision ranging commonly employs phase distance sensors, known for their high accuracy typically at the millimeter level.
