Designing a point diffraction interferometer
This tech talk goes into the details of designing and using a phase-shifting point diffraction interferometer. This is an easy to build and insensitive high-accuracy tool that removes all guess-work from understanding the optical performance of any high-end optical projection system.

Point Diffraction Interferometer
The point-diffraction phase-shifting interferometer is perhaps the most accurate instrument that can be made and adapted to imaging systems.
Wavefront metrology
Wavefront metrology and phase-shifting interferometry will take the guessing out of your optical systems.
