Since this new approach allows the researchers to choose their focus as and when they will, it's more akin to exchanging lenses in a normal optical setup.

Figure 2 demonstrates optical setup of shearing interferometer with air-wedge.

The practical details: hardware (optical setups) and software (optical templates) are published.

It is possible to design an optical setup with an arbitrary filter function which can be complex-valued, as long as .

This technique features with full calibration and control of the ultrashort pulse, with no moving parts, and simple optical setup.

A reconstruction algorithm that truly models the optical setup will not suffer from optical aberrations.

This optical setup enables determination of the distance between the two surfaces.

Additionally, the optical setup of such systems is much simpler because the residual light does not need to be separated and recombined at a different location.

The optical setup of a Schlieren imaging system may comprise the following main sections:

The SNAP will use an optical setup called the three-mirror anastigmat.
