Image based wavefront compensation with deformable mirror for small satellite remote sensing

We are developing an adaptive optics system for earth observing remote sensing sensor. In this system, high spatial resolution and high signal to noise ratio has to be realized by a lightweight sensor system due to the launcher’s requirements. Moreover, simple hardware architecture has to be used to achieve high reliability, low cost, and short development period. Image based AOS realize these requirements without wavefront sensor. In remote sensing, it is difficult to use a reference point source unless the satellite controls its attitude toward a star. We propose the multi-mode phase diversity method using deformable mirror.
