Laser Measurement
Laser ranging is a method that uses laser beams to measure distance. Its basic principle involves emitting a laser pulse toward the target object and starting a timer, then stopping the timer upon receiving the reflected light. The elapsed time can be converted into distance between the laser device and the target. Laser rangefinders can also emit multiple laser pulses and use the Doppler effect to determine whether an object is moving away from or approaching the light source.

Distance Measurement
Distance is calculated by measuring the round-trip time or phase difference of a laser beam, and this technique is widely used in fields such as construction, surveying, and mapping.

Profile Measurement
By rapidly scanning a laser beam, the surface profile of an object can be captured. This method is applicable to reverse engineering, 3D modeling, and cultural artifact replication.
