The large adaptive deformable mirrors were adapted in several large aperture telescopes and has been proved to have great effect in the AO system, however the captive sensors used in the adaptive secondary are very sensitive to the circumstance such as temperature, moisture, dust, So a new adaptive mirror scheme using the Eddy Current Sensors has been proposed

in this paper.

The technical plan would be discussed in this paper, a number of simulations would be carried out and some experiments result would be posed in this paper.
