Abstract: A detector system for Fourier spectroscopy such as a spectral domain optical coherence tomography instrument includes a diffractive optic for diffracting the interfering light into angularly dispersed wavenumbers, a prism for reduces a nonlinear angular dispersion among the wavenumbers, and a focusing optic for converting the angularly dispersed wavenumbers from the prism into spatially distributed wavenumbers along a detector having an array of pixels. A field lens between the focusing optic and the detector has a freeform surface for more evenly distributing the wavenumbers along the array of pixels.

Abstract: A see-through reflective optical device includes: a reflective metasurface configured for a targeted design optical wavelength, wherein the reflective metasurface comprises a sub-wavelength periodic arrangement of meta-atoms formed by patterned isolated gap surface plasmon (GSP) resonators, where the patterned isolated GSP resonators comprise a patterned optically thin metal layer for the design wavelength, an optically thick metal layer for the design wavelength, and an insulator layer between the patterned optically thin metal layer and the optically thick metal layer; and an array of apertures of random positions and diameters greater than the targeted design wavelength formed through the reflective metasurface providing a designed percentage of light transparency through the reflective metasurface. The reflective metasurface of the see-through reflective optical device may comprise, e.g., a reflective diffraction grating metasurface, and may be used as a combiner element surface in a near eye display assembly.

Abstract: A near eye display assembly includes (a) frame; (b) a combiner operably connected to the frame as a first reflective surface positionable in front of an eye of a user of the display assembly; (c) a secondary mirror operably connected to the frame as a second reflective surface positionable proximate a side of the nose adjacent to the eye of a user of the display assembly; (d) an image source operably connected to the frame and optically coupled to the secondary mirror along an optical path; and (e) an optical fold element between the image source and the secondary mirror in the optical path, and positionable proximate the temple adjacent to the eye of a user of the display assembly; wherein an intermediate image is formed in the optical path between the image source and the secondary mirror, wherein the combiner and the secondary mirror are in an off-axis folded geometry which directs images from the optical fold element to an eyebox of the near eye display assembly, and at least one of the combiner and the secondary mirror include a freeform surface, wherein the freeform component corrects optical aberrations induced by a tilting and decentering of the first reflective surface and the second reflective surface, and wherein at least the combiner includes a nanostructured meta-surface which further provides wavefront control of an image from the image source to be directed to the eyebox and enables the combiner to be positioned at a tilt angle so that unobscured images are conveyable between the optical fold element and the secondary mirror while providing an FOV of at least 30 degrees and an eyebox width of at least 5 mm.

Abstract: An echelle spectrometer includes a slit opening for incoming light, a collimator which collimates a diverging beam of light generated through the slit, a reflective echelle grating which disperses the collimated light along a first dimension; a cross-disperser which disperses at least a portion of the collimated light in a second dimension orthogonal to the first dimension to create a two-dimensional spectral field-of-view; and an imaging system which images the two-dimensional spectral field-of-view onto a detector; wherein the imaging system comprises primary, secondary, and tertiary tilted mirrors, where each of the tilted mirrors comprises a freeform, rotationally non-symmetric surface shape.

Abstract: A near eye display includes at least one of a combiner, a secondary mirror, and a waveguide having a freeform nanostructured surface. The freeform nanostructured surface encompasses a freeform surface, a nanostructured surface or a combination of both the freeform surface and the nanostructured surface. The freeform nanostructured surface can be incorporated into a combiner or a secondary mirror in the near eye display in a compact folded geometry, wherein an anamorphic or freeform optic can be optically intermediate an image source and the freeform nanostructured surface. The nanostructured surface can include a meta-grating operable across the visible spectrum. The meta-grating includes meta-atoms configured to provide a given efficiency at the desired wavelengths in reflection.
