Paper Abstract

A kind of new adaptive optics (AO) configuration, for which several deformable mirrors (DMs) with optical conjugation relationships are combined to correct high-order aberrations, is proposed. Based on theoretical analysis and numerical simulation, an integrated AO system with combinational-deformable-mirror (CDM) that consisted of two same deformable mirrors is built, and its correction capability is validated experimentally. The results indicate that the CDM in the AO system correct aberrations effectively as same as one single DM with more actuators by using the direct-gradient control algorithm in closed-loop. This design can improve wavefront spatial correction capability by increasing the number of actuators and the coupling coefficient. So it can be used for compensating high-order aberrations instead of one single costly DM with more actuators for the same performance.
