International Classification:

G01B 11/02

US Classification:

356497, 356479, 356517

Abstract:

A system and method for microscale measurement and imaging of the group refractive index of a sample. The method utilizes a broadband confocal high-numerical aperture microscope embedded into an interferometer and a spectrometric means, whereby spectral interferograms are analyzed to compute optical path delay of the beam traversing the sample as the sample is translated through the focus of an interrogating light beam. A determination of group refractive index may serve to disambiguate phase ambiguity in a measurement of refractive index at a specified wavelength. Spatial resolution of object characterization in three dimensions is achieved by imaging the object from multiple viewpoints.

International Classification:

G01B 9/02

US Classification:

356451

Abstract:

Methods and apparatus for selectively driving the vibrations of normal modes of a target molecule into coherence using stimulated Raman scattering. In concert, many vibrations produce a larger anti-Stokes signal than a single vibration. The same illumination does not drive other molecules to have coherent vibrations, so these molecules produce a weaker signal. Target and confounder molecules can be distinguished by pulses that drive many vibrations coherently, with applications in coherent Raman microspectroscopy.

Assignee:

DUKE UNIVERSITY - Durham NC

International Classification:

H04N 5/225

US Classification:

348340, 348E05028

Abstract:

A monocentric lens-based multi-scale imaging system is disclosed. Embodiments of the present invention comprise a monocentric lens as an objective lens that collects light from a scene. Monocentric lenses in accordance with the present invention include a spherical central lens element and a plurality of lens shell sections that collectively reduce at least one of spherical and chromatic aberration from the magnitude introduced by the spherical lens element itself. A plurality of secondary lenses image the scene through the objective lens and further reduce the magnitude of aberrations introduced by the objective lens. A plurality of sensor arrays converts optical sub-images of the scene into a plurality of digital images, which can then be used to form a composite image of the scene.

Assignee:

International Classification:

H04N 13/02

US Classification:

348 46, 348E13074

Abstract:

A method and system for forming a three-dimensional image of a three-dimensional scene using a two-dimensional image sensor are disclosed. Formation of a three-dimensional image is enabled by locating a coded aperture in an image field provided by a collector lens, wherein the coded aperture modulates the image field to form a modulated image at the image sensor. The three-dimensional image is reconstructed by deconvolving the modulation code from the image data, thereby enabling high-resolution images to be formed at a plurality of focal ranges.

International Classification:

H04N 13/02

US Classification:

348 47

Abstract:

A multiscale imaging system including microcameras having controllable focus, dynamic range, exposure, and magnification is disclosed. The objective lens forms a three-dimensional image field of a scene. Image regions of the image field are relayed by the microcameras onto their respective focal-plane arrays, which collectively provide a plurality of digital sub-images of the scene. The digital sub-images can then be used to form a composite digital image of the scene that can have enhanced depth-of-field, enhanced dynamic range, parallax views of the scene, or three-dimensionality.

International Classification:

G01S 13/88

US Classification:

342 22

Abstract:

Compressive imaging captures images in compressed form, where each sensor does not directly correspond with a pixel, as opposed to standard image capture techniques. This can lead to faster image capture rates due to lower I/O bandwidth requirements, and avoids the need for image compression hardware, as the image is captured in compressed form. Measuring the transformation of an emitted multimodal signal is one method of compressive imaging. Metamaterial antennas and transceivers are well suited for both emitting and receiving multimodal signals, and are thus prime candidates for compressive imaging.

International Classification:

G03H 1/26

Abstract:

Various examples of out-of-plane multicolor waveguide holography systems, methods of manufacture, and methods of use are described herein. In some examples, a multicolor waveguide holography system includes a planar waveguide to convey optical radiation between a grating coupler and a metasurface hologram. The grating coupler may be configured to couple out-of-plane optical radiation of three different color incident at three different angles into the planar waveguide. The combined multicolor optical radiation may be conveyed by the waveguide to the metasurface hologram. The metasurface hologram may diffractively decouple the three colors of optical radiation for off-plane propagation to form a multicolor holographic image in free space.
