  • Retroreflector having a curved surface
    Patent number: 11029456
    Abstract: A retroreflector has an arrangement of triples, each having three side surfaces that stand essentially perpendicular on one another. The triples are disposed on a curved or domed surface. The geometry of the triple array is adapted to the curved surface, to even out the thresholds, and extend the side surfaces of a triple. The extensions of the side surfaces project into adjacent triples. Due to the extension projecting into adjacent triples, joints are formed there, which even out the uneven area. The joints can assume the form of a protrusion filled with material or a notch in which material is missing. A forming die produces the retroreflector and a method produces the forming die. The retroreflectors have geometries having full cube surfaces, in other words Full Cubes, for curved or domed surfaces or free-form surfaces.

  • Switchable optical filter for imaging and optical beam modulation
    Patent number: 11022823
    Abstract: switchable optical filter that is based on carrier injection induced semiconductor to metal phase transition (SMT) of vanadium oxide-based (e.g., VO2) thin films may reversibly change from optically transparent to opaque while undergoing such phase transition. Electrical carrier injection may be established by an electric field or by photoexcitation. The SMT may also be induced by a combination of applying an electric field and optical flux. Such a switchable optical filter, when inserted in the optical path of an optical radiation sensor, may be used to control and/or limit high power optical beams, such as a laser beam impinging on one or more sensor elements. Since the SMT may be configured to occur at ultrafast time scales (e.g., approximately 100 femtoseconds), it may also act as a beam shutter and/or as a fast optical beam modulator.
