Abstract

This paper proposes the implementation of a self-deformation estimation strategy for an active mirror within a framework of mechanoelectrical sensing. This architecture can collaborate with conventional optical wavefront sensors in a complementary manner, integrating information from various working bands and noise levels. The aim is to enhance the shape maintenance of the Active Optics mirror and improve its capability to reject disturbances from external sources. The paper firstly discusses the theoretical background of relative shape detection, providing examples such as voice coil Deformable Mirrors with an out-of-plane actuator/sensing architecture. Then, it illustrates the transverse sensing of the mirror surface in modal coordinates, with applications on stacked piezoelectric mirrors and unimorph Deformable Mirrors. Finally, a design of the active mirror for space Active Optics with internal actuator/sensor units is proposed.
