| Zusammenfassung: | Systems and methods for shifting the phase of incident light to induce a continuous phase variation in an azimuthal direction. A phase mask apparatus includes a conical mirror assembly and a flexible annular reflector that substantially surrounds at least a portion of the conical mirror assembly. The flexible annular reflector is configured to receive reflected light from the conical mirror assembly. A plurality of driver assemblies are operative to deform the flexible annular reflector as to produce the desired phase response in light reflected from the annular reflector. |
