TimeofFlightsystem
TimeofFlightsystem is a measurement technology that determines distance to a target by calculating the time elapsed between sending a probing signal and receiving its reflection. It is commonly based on the time of flight of light, though similar methods use acoustic signals. TimeofFlightsystem is used in applications such as 3D imaging, depth sensing, robotics, and range finding.
Two main implementations exist: pulsed direct ToF and phase-based indirect ToF. Direct ToF measures the actual
Components typically include a light source, optics, a photodetector, timing electronics or phase detectors, and a
Applications span LiDAR for autonomous vehicles, consumer depth sensors in smartphones, industrial automation, and gesture recognition.
