Abstract: An exemplary method and system are disclosed comprising retroreflective metastructures formed with a plurality of metasurface arrays configured to destructively cancel or interfere, in part, with one another to reduce specular mode associated scattering or reflection. In some embodiments, the retroreflective metastructures are formed by a combination of metasurfaces with different lattice spacings that can exhibit enhanced bandwidth and angular range at near-grazing angles to provide enhanced retroreflective electromagnetic responses.

Abstract: A LED panel wherein a plurality thereof are employed to construct a LED volume for filing simulated virtual environments wherein the LED panel of the present invention provides tracking of objects in the vicinity thereof such as but not limited to a camera wherein the tracking elements do not require post production removal. The LED panel includes a housing having a perimeter frame that has a transparent LED display mounted thereto. On the rear surface of the LED display or proximate thereto are a plurality of retroreflectors. The retroreflectors function to provide inside-out tracking of a camera disposed within the LED volume. The present invention further includes a plurality of lidar sensors and optical sensors mounted to the perimeter frame. The lidar sensors and optical sensors provide data for outside-in tracking of a camera within the LED volume. The retroreflectors can be provided in multiple alternate embodiments.

Abstract: A compact wavelength dispersing device and a wavelength selective optical switch based on the wavelength dispersing device is described. The wavelength dispersing device has a folding mirror that folds the optical path at least three times. A focal length of a focusing coupler of the device is reduced and the NA is increased, while the increased optical aberrations are mitigated by using an optional coma-compensating wedge. A double-pass arrangement for a transmission diffraction grating allows further focal length and overall size reduction due to increased angular dispersion.
