Abstract: A spectrally-shaped source includes a source that generates a round beam. An optical element transforms the round beam to a rectangular beam. An image forming dispersive device angularly disperses wavelengths and images the rectangular beam at a modulation plane. A pixelated SLM is illuminated by the dispersed wavelengths of the rectangular beam such that each column of illuminated pixels is illuminated by a different wavelength. Toroidal optics projects light directed from the SLM to an output plane and focuses the angularly dispersed wavelengths of the beam so that a selected portion of the optical beam is reflected toward the toroidal optic by the SLM. A controller instructs the pixelated SLM to selectively reflect the portion of the optical beam toward the toroidal optic and to selectively reflect another portion of the beam away from the toroidal optic so as to provide a desired spectral shape.

Abstract: The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.

Abstract: A method and apparatus is provided for calibrating a Fabry-Perot etalon based optical measurement system. The calibration is performed by analyzing the shape of transmission peaks output from the etalon in response to a known optical signal and using that information, along with a formula that approximates the response of the etalon, to perform the calibration.

Abstract: A method of forming a continuous film of an elastomeric latex and a phenolic resin comprising spraying a plurality of coats of the aqueous admixture onto a nonadherent surface. The nonadherent surface is at a temperature of 120.degree. F. or greater and each coat of the aqueous admixture is less than about 0.7 mil dry film thickness. The film so formed can be tested for physical properties and the testing results are capable of being correlated with the performance of glass fibers with the aqueous admixture coated thereon for reinforcement of elastomeric matrices.
