Working Principle

The measured distance can be expressed as: 2L = Δφ × c × T / 2π

In this formula, L represents the measured distance, c is the speed of light in air, T is the period of the modulated signal, and Δφ is the phase difference between the transmitted and received modulated light.

Phase-based laser distance sensor offers advantages such as high measurement accuracy, a wide measurement range, and strong resistance to interference, making it widely used in fields such as industry, surveying, and remote sensing.
