Achromatic and Polarization Adaptive Optics System
This invention is an adaptive optics (AO) system for broadband and/or polarization dependent light. The system includes a wavefront sensor and compensator, and the compensator splits the broad waveband into different wavelength and/or polarization states, applies compensation, then recombines the light into a single wavefront with distortions that may...
