Laser Distance Measuring Meter typically consist of the following main components

Laser Emitter: A device that generates a pulsed laser beam. It can emit high-energy, high-frequency, and short pulse laser beams.
Receiver: Receives laser signals reflected back from the target object and converts them into electrical signals for processing. The receiver typically includes optical components, photodetectors, and signal amplifiers.
Control Circuit: responsible for controlling the timing of laser emission and reception, ensuring their coordinated operation. The control circuit can also include other functions, such as triggers, clock sources, and timing circuits.
Distance Calculation Module: calculates the distance between the target object and the rangefinder based on information such as laser return time or phase difference. This module typically includes timers, phase difference measurement circuits, and distance calculation algorithms.

Display or Data Output Interface: Displays the measured distance information in a visual form to the user, usually connected to a computer or other device through a built-in display or external interface.

In addition to the main components mentioned above, laser distance meter range may also be included, such as power supply, control buttons, memory, and communication interfaces, to provide more functionality and convenience.
