Paper Abstract

The multiaperture overlap-scanning technique (MAOST) is a new method for large optics testing. We describe the mathematical model and the performance procedure of the transformation and connection of subapertures for MAOST. Computer simulation results show that the theoretical accuracy of a pair of two-subaperture connections tested with MAOST could be reached up to λ/600. The experimental test with a magnification ratio of 1.7 in a four-aperture overlap-scanning configuration is conducted and its result is analyzed in detail
