Abstract: A compact conical diffraction Littrow spectrometer is disclosed. The distortion of the conically diffracted spectral component beams is compensated and as a result, the diffracted spectral beams can still be focused into a substantially straight line to shine onto a detector array. A spectral domain optical coherence tomography (SD-OCT) system incorporating a Littrow spectrometer or a spectrometer having one or more shared focusing element(s) and an SD-OCT system incorporating a spectrometer that is substantially polarization independent are also disclosed.

Abstract: A two dimensional spatial radiation modulator rotated about a rotation axis to modulate components of an incident radiation beam to encode the beam. The modulator includes sub-regions in a first annular segment being patterned to form a pair of radiation filters having substantially complementary modulation functions. The pair of radiation filters produces a first encoded component with a characteristic determined by the relative intensities of radiation from the beam incident on the pair of filters. The modulator also includes sub-regions in a second annular segment being patterned to form a filter that produces a second encoded component with a characteristic determined by the total intensity of radiation from the beam incident on the filter.

Abstract: A light fixture converts source light from one or more solid state light emitting elements to a virtual light source output. An optical element receives and diffuses light from the solid state emitters to form a processed light for the virtual source output. The optical element forms light that is relatively uniform, for example having a substantially Lambertian distribution and/or having a maximum-to-minimum intensity ratio of 2 to 1 or less over the optical area of the virtual source. In the examples, the diffuse optical processing element comprises a cavity having at least one diffusely reflective surface, and the emitting elements supply light into the cavity at locations that result in reflection and diffusion before emission through an aperture of the cavity. The aperture or a downstream processing element appears as the virtual source of the processed light from the cavity.

Abstract: A light fixture, using one or more solid state light emitting elements, provides an unpixelated light output. An optical element receives and diffuses light from the solid state emitters to form a processed light for output via an optical output area of the fixture. The optical element forms light that is relatively uniform, for example having a substantially Lambertian distribution and/or having a maximum-to-minimum intensity ratio of 2 to 1 or less over the optical output area. In the examples, the optical element comprises a cavity having at least one diffusely reflective surface, and the emitting elements supply light into the cavity at locations not visible through an aperture of the cavity that forms the optical output area. Hence, light from the emitting element(s) is diffusely reflected one or more times within the cavity before emission as part of the uniform light output through the aperture.

Abstract: An apparatus for selectively producing one or more of a plurality of wavelength distributions of radiation. The apparatus comprises a primary UV radiation source and one or more wavelength transforming materials separated from the primary UV radiation source, that in response to irradiation by the primary UV radiation source, produce transformed radiation having a wavelength distribution that is different from the wavelength distribution of the primary UV radiation source. None, one, or more than one of the various WT materials can be selected by the apparatus, to allow the primary UV radiation, any individual transformed radiation, or any combination of the various radiations to be to be emitted from the apparatus.

Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associated color of a structure is also provided.
