ToF
A time-of-flight sensor (ToF) is used for measuring distance by timing the round-trip of an EM modulated wave, such as Light, Infra-red or radar signals. When the sensor is used to form images it is known as a ToF camera e.g. a LIDAR system.
Some LIDAR systems are point-to-point ToF e.g. the DfRobot 1702[1] sensor.
