(physics, chemistry) a technique of separating ions of different masses by measuring the time taken to traverse a fixed distance through a magnetic field

A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.

Time-of-flight diffraction method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects.
