Laser Sensors - Basics

Laser sensors work using a highly amplified and coherent radiation at one or more frequencies, in a similar way that sonar use sound. 20210602190915. They don’t use time-of-flight measures, since light travels way faster that sound. They use phase-shift to calculate the distance.

Lasers are not affected by specular reflection, in contrast to sonar sensors, and are more accurate that sonars. In contrast, laser sensors are bigger than sonars, require more power to operate and are more expensive that sonars.
