Basic time-of-flight principles applied to laser range-finding. Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or ...
6 maj 2024 · The time of flight (ToF) sensor measures the distance between two points using the ToF principle using light or sound. A signal, usually light photons, is sent from the sensor's emitter to the target and then received back at the sensor receiver. The time taken by the signal helps measure the distance.
Time-of-flight mass spectrometry ( TOFMS) is a method of mass spectrometry in which an ion 's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. [1] . This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge.
The time of flight is proportional to the square root of the mass of the ions, showing that the lighter the ion the faster it will pass through and the quicker it will hit the detector. The heavier the ion, the slower it will travel and the longer it will take to hit the detector.
tor. The flight time (t) is determined by the energy (E) to which an ion is acceler-ated, the distance (d) it has to travel, and its mass (strictly speaking its mass-to-charge ratio). There are two well know formulae that apply to time-of-flight analysis. One is the formula for kinetic energy: E = 1/2mv2 which is solved for m looks like: m = 2E ...
Time of Flight, T: The time of flight of a projectile motion is exactly what it sounds like. It is the time from when the object is projected to the time it reaches the surface. The time of flight depends on the initial velocity of the object and the angle of the projection, θθ.
Time of flight refers to the duration of the entire projectile motion: from the time of launch to the time when it reaches its destination. Time of flight is affected by initial vertical component velocity. It is not affected by initial horizontal component of velocity. Calculating time of flight is usually associated with the following equation:
