Abstract

We describe a thorough processing procedure of experimental data from annular subaperture measurents, in which the crucial reconstruction algorithm is based on Zernike annular polynomials and matrix method. The result of simulation is satisfactory, and the proposed method is easier to implement than that of those overlapping annular subaperture interferometry. In addition, experimental results of testing parabolic mirror with about 700-mm diameter and 0.228 obscuration are also provided, and some limitations and considerations are discussed.
