Working Principles of 3D Scanning Laser Modules

The working principles of laser scanning modules are based on either laser triangulation or the time-of-flight method. Laser triangulation involves projecting a laser beam onto an object's surface and using a detector to capture the reflected light; the distance to the surface is then calculated based on the angles of incidence and reflection. The time-of-flight method calculates distance by measuring the time it takes for the laser beam to travel from the emitter to the object and back. Both methods enable the efficient acquisition of high-precision 3D data.
