Simultaneous multi-segmented mirror orientation test system using a digital aperture based on sheared Fourier analysis

This paper presents a simultaneous multi-segmented mirror orientation test system (SMOTS) using localized sheared images. A CMOS camera captures images of reflected 2D sinusoidal patterns from the test mirrors as their orientation changes. Surface orientation is measured to within 0.8 mu rad (0.16 a...
