Computational imaging using low-order unimorph deformable mirror

We present the integration of a low-order unimorph deformable mirror into an optical system for reconfigurable high-speed imaging and metrology. With the deformable mirror it is possible to precisely control four Zernike aberrations: tip, tilt, defocus and astigmatism. In conjunction with a high speed camera and a dedicated optical system, the deformable mirror opens a flexible way to change the optical transfer function as required for computational imaging applications. In the presented work, a wide range of applications is reviewed and various different optical arrangements are discussed. A prototype version of the reconfigurable optical system has been developed and built. We present the preliminary acquisition of image data with adaptive optical transfer function.
