TL;DR: Feedback from a self-pumped BaTiO(3) phase-conjugate reflector into an untuned cw dye laser produces substantial line narrowing and generates a recurrent wavelength sweep from the rhodamine 6G peak at 618 nm to as far as 644 nm.
Abstract: Feedback from a self-pumped BaTiO3 phase-conjugate reflector into an untuned cw dye laser produces substantial line narrowing (4–6 GHz) and generates a recurrent wavelength sweep from the rhodamine 6G peak at 618 nm to as far as 644 nm.

TL;DR: In this article, an apparatus and method for measuring spatially varying bidirectional reflectance distribution function and method is provided, which provides means to illuminate different areas of a sample at different angles of incidence and detect the angular variation of radiation emitted from the sample in response to the illumination.
Abstract: An apparatus and method for measuring spatially varying bidirectional reflectance distribution function and method are provided. The apparatus and method provide means to illuminate different areas of a sample at different angles of incidence and detect the angular variation of radiation emitted from the sample in response to the illumination. The apparatus includes a paraboloidal reflector for delivering the illumination and receiving the radiation emitted by the sample, a radiation source for generating a beam of collimated radiation, a beam steering device for controlling the angle of incidence with which the focused cone of light strikes the sample, and a detector to receive the collected light from the reflector.

10 Feb 2010TL;DR: In this article, a scanning reflector surface is configured to be rotated about two axes in a single operating plane to direct light transmitted along the sample path to a sample to be imaged.
Abstract: Provided are forward-imaging optical coherence tomography (OCT) systems and probes. In one embodiment, a scanning reflector surface is configured to be rotated about two axes in a single operating plane to direct light transmitted along the sample path to a sample to be imaged.

23 Oct 1975TL;DR: In this paper, a spoked wheel-shaped supporting structure for storing, deploying and supporting surfaces such as radar and communications antennas, shielding, earth sensing, solar cell arrays and solar energy reflectors is described.
Abstract: A supporting structure that deployed resembles a spoked wheel which is retractable into a compact volume by virtue of hinged rim and reelable spokes that is an efficient and stable structure for storing, deploying and supporting surfaces such as radar and communications antennas, shielding, earth sensing, solar cell arrays and solar energy reflectors.
