Laser sensors are devices that use laser technology to detect, measure, or sense objects or changes in the environment with high precision. They operate by emitting a focused beam of light (the laser) and analyzing the light that reflects back from a target, enabling non-contact measurements. This makes them valuable across industries like manufacturing, robotics, and automation.
Types of Laser Sensors
Laser sensors come in various types, each designed for specific purposes:
Distance Sensors: Measure the distance to an object using the time-of-flight principle (calculating the time it takes for the laser to return) or triangulation methods.

Proximity Sensors: Detect whether an object is present or absent within a specific range.

Displacement Sensors: Measure tiny changes in an object’s position, often used for precision tasks like quality control.

Speed Sensors: Calculate an object’s speed by analyzing the Doppler shift in the reflected laser light.

Gas Sensors: Identify specific gases by measuring how they absorb laser light at certain wavelengths.
