  • Patent number: 12085445
    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.

  • Patent number: 10371951
    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.
