Axially Scanning to Determine Slopes of Aspheric Surfaces
Researchers at the University of Arizona have developed a system for testing the figure and finish of optical surfaces or any other curved surface using a Shack-Hartmann type of method, wherein a pattern can be projected onto the surface and then its returned image can be analyzed. The patterns can be varied to optimize the returned information regarding...
