Adaptive / Active optics are now an essential tool for exploiting the full potential of synchrotron and free electron laser sources, especially for challenging applications such as: nanofocusing, coherence and wavefront preservation, and lens-less diffraction imaging. Via invited talks and contributed oral / poster presentations, the workshop will provide a forum for scientists, engineers, and industry to exchange ideas on the latest advances in adaptive and active optics, and to discuss future requirements and challenges.
