These images as well as their associated numerical results can be saved in computer files. The other program helps in the design of phase shifting algorithms with the desired properties by using its ...

In theory, the ideal Mach Zender interferometer would have identical path lengths (without the sample). However, this is not a strict requirement, since a phase shift of an integer number of wave ...

Interferometers can be considered specific cases of array antennas. The linear array in which all antenna elements center lie in a straight line at equal spacings with beam forming done by phase shift ...

Multiple frames can be acquired in many different ways. The reference in a “phase-shifting” Fizeau interferometer is shifted in accurate increments corresponding to the test surface. Such increments ...

This capability provides consistent metrology in environments that are too aggressive for conventional temporal phase shifting methods. Additionally, the interferometer is capable of capturing and ...
