Multi-object wavefront sensor with spatial filtering

• The present invention relates to an adaptive optics sensor intended for simultaneous detection of several wavefronts on a common camera target. The sensor is intended for use in connection with multi-conjugate adaptive optics (MCAO), where several wavefront measurements are needed at the same time. The sensor includes a spatial filter taking out signals resulting from parasitic reflections of the reference sources and from unwanted parts of the object.
