Laser Encoders

Laser encoders are high-precision optical measurement systems used for displacement and positioning control by utilizing a laser beam to monitor linear or angular movement of objects.

They combine the ultra-high accuracy of laser interferometry with the compactness and ease of installation of traditional encoders, ensuring stable motion control even in the most demanding industrial environments.

Unlike conventional mechanical or magnetic measuring systems, laser encoders operate without physical contact, minimizing mechanical wear and ensuring maximum equipment durability.

Thanks to laser technology, these systems provide extremely high resolution and repeatability in measurement processes.

Purpose and Capabilities

Laser encoders are used for:

high-precision positioning of axes and mechanisms;
control of linear and angular displacement;
motion speed measurement;
synchronization of high-speed processes;
monitoring the accuracy of machine operation;
feedback in servo drives and automated systems;
high-precision motion control in robotic systems.

Operating Principle

A laser encoder directs a laser beam onto a special scale or surface and analyzes the reflected light.

As the object moves, the parameters of the laser interference pattern change, allowing the system to instantly determine position, direction of movement, and speed with maximum accuracy.

The acquired data is converted into a digital signal for equipment control systems.

Main Types of Equipment

The category of laser encoders includes the following types of systems:

linear laser encoders — for monitoring movement along linear axes;
