Tip/tilt Alignment for a Fizeau Interferometer via Defocus-Based Sub-Spot Separation
It is a crucial premise for Fizeau interferometric imaging that all the optical axes of sub-apertures are well aligned. What is challenging in tip/tilt alignment of such interferometers is the superposition of all the sub-aperture spots on the focal plane for generation of fringes. In this paper, we...
