Comparation of Non-null Figure Error Reduction Methods in Testing Deep Aspherics with Large Errors

Not Accessible

Your library or personal account may give you access

Abstract

Four commonly used figure error reduction methods for aspheric surface error in a non-null test are discussed and compared. Simulations are presented to show the behaviors of the four methods in the case of testing a deep aspheric with large figure error in a non-null test.
