Pulsed systems use signal timing to obtain vertical distance resolution, whereas continuous wave systems rely on detector focusing.
3.
Momentum transfer is an important quantity because \ Delta x = \ hbar / | q | is a better measure for the typical distance resolution of the reaction than the momenta themselves.
4.
If we change the shape of the pulse in a specially-designed way, the signal-to-noise ratio and the distance resolution can be even improved after matched filtering : this is a technique known as pulse compression.
5.
The object being imaged is then moved in high-precision steps through the wave field, or the wave field itself is moved relative to the object by phase shift . This results in an improved axial size and distance resolution.
6.
The SMI microscopy approach used in the Heidelberg application moves the object in high-precision steps through the wave field, or the wave field itself is moved relative to the object by phase shift . This results in an improved axial size and distance resolution.
