What Are TOF Distance Detection Sensors?<\/h3>\n\n\nTOF distance sensors (\ube44\ud589 \uc2dc\uac04 \uc13c\uc11c<\/a>) measure distance by calculating how long it takes for a light signal to travel to an object and back to the sensor. Typically, a light pulse, often in the form of laser or LED light, is emitted towards the target object. The light reflects off the object, returns to the sensor, and the sensor measures the time it took for the light to travel the round trip.
Since light travels at a known speed (about 299,792 kilometers per second), even tiny time differences can translate into highly accurate distance measurements, making TOF \uc13c\uc11c<\/a> invaluable for many high-precision applications.<\/p>\n\n<\/div>\n<\/div>\n\nHow Do TOF Distance Sensors Work?<\/h3>\n\n\nThe working principle of a TOF \uac70\ub9ac \uc13c\uc11c<\/a> is simple, involving just a few key steps:
Emission of Light Pulse<\/strong>: The sensor emits a pulse of light\u2014usually a laser or LED light\u2014toward the target object.
Light Reflection<\/strong>: Once the light reaches the object, it reflects back toward the sensor. The sensor detects the reflected light.
\uce21\uc815 \uc2dc\uac04<\/strong>: The sensor calculates the time it took for the light pulse to travel to the object and back. This is called the “time-of-flight.”
\uac70\ub9ac \uacc4\uc0b0<\/strong>: Using the formula:the sensor calculates the distance to the object, dividing by two to account for the round-trip travel of the light.
