Source: MDPI Understanding Time-of-Flight Measurements Time-of-flight measurements are commonly used for distance measurements, such as in laser rangefinders or scanning laser radars. In this method, a short light pulse is emitted, and the time taken for a reflected portion of the pulse to return is measured. The distance is then calculated based on the round-trip
