Time of Flight and Triangulation: Which Laser Distance Sensor is Right for You?<\/h3>\n
\n\"phase\n

When exploring laser measurement<\/a> technologies, two common methods stand out: time of flight and triangulation. Both offer distinct advantages depending on your project needs. In this guide, we\u2019ll dive deep into time of flight and triangulation laser distance sensors<\/a>, comparing their working principles, pros and cons, and best-fit applications. By the end, you’ll know which solution is right for your business.<\/p>\n\n<\/div>\n<\/div>\n

What is a Time of Flight and Triangulation Sensor?<\/h3>\n
\n\"\"\n

While both time of flight and triangulation are used in laser distance<\/a> sensing, they function very differently.
Time of flight sensors<\/a><\/strong> calculate distance by measuring how long it takes a laser to travel to a target and back.
Triangulation sensors<\/strong>, on the other hand, measure distance using geometric angles and laser reflection.
In this section, we\u2019ll break down how time of flight and triangulation technologies work.<\/p>\n\n<\/div>\n<\/div>\n

How Time of Flight and Triangulation Work<\/h3>\n
\n\n

Time of flight and triangulation sensors are based on two different measurement principles:
A time of flight<\/strong> sensor emits a laser pulse and calculates distance based on how long it takes for the light to return.
A triangulation<\/strong> sensor projects a laser spot and measures the angle of reflection to determine distance.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
