Abstract
An apparatus for testing an optical surface comprising an array of holograms. The array includes a plurality of individual holograms arranged in an M×N format, in which M is the number of rows and N is the number of columns in the array. The array of holograms is positioned between the optical surface and a wavefront sensor. The array of holograms reflects a reference beam back to the wavefront sensor, and transmits a test beam to the optical surface. The array of holograms also receives the test beam reflected from the optical surface and transfers the test beam back to the wavefront sensor.
