The effectiveness of using an adaptive four-element segmented mirror, each element of which makes adjustments only for the tilts in two perpendicular directions, is investigated. An optical arrangement of the experiment is proposed. The wavefront sensor consists of four identical devices for measuring the position of the center of gravity of the image within each subaperture. The limiting resolution for such an optical system is analyzed.
