Time of Flight. The simplest way to think about âtime of flightâ laser scanning is to look approach it as nothing more than a laser range finder. I think we all understand how a laser range finder works. It basically measures a distance by shooting a laser beam out to an object and measuring how long it takes that laser beam to bounce back.
This page describes how a mass spectrum is produced using a mass spectrometer. How a mass spectrometer works. The basic principle. If something is moving and you subject it to a sideways force, instead of moving in a straight line, it will move in a curve-deflected out of its original path by the sideways force.n outline of what happens in a mass spectrometer Atoms and molecules can be deflected by magnetic fields-provided the atom or molecule is first turned into an ion. Electrically charged particles are affected by a magnetic field although electrically neutral ones aren't.
