Background-oriented schlieren technique (BOS [7]) relies on measuring or visualizing shifts in focused images. In these techniques, the background and the schlieren object (the distortion to be visualized) are both in focus and the distortion is detected because it moves part of the background image relative to its original position.

In physics and astronomy, a frame of reference (or reference frame) is an abstract coordinate system, whose origin, orientation, and scale have been specified in physical space. It is based on a set of reference points , defined as geometric points whose position is identified both mathematically (with numerical coordinate values) and ...
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
