Abstract: A vehicle rearview mirror system includes an electro-optic reflective element, an ambient light sensor that is operable to sense ambient light, a glare light sensor that is operable to sense glare light and a circuit that is responsive to the ambient glare light sensors which establishes a reflectance level of the reflective element. The circuit includes a sensor-responsive device and a controller. The sensor-responsive device produces an output that is a function of light sensed by glare and ambient light sensors. The controller connects one of the glare and ambient light sensors at a time with the sensor-responsive device to establish glare and ambient light levels and thereby the reflectance level of the reflective element. The mirror system may include a display operable to project light through the reflective element and may control the intensity of the display as a function of the glare light and ambient light.

Abstract: An optical apparatus for producing chromatic dispersion. The apparatus includes a virtually imaged phased array (VIPA) generator, a mirror and a lens. The VIPA generator receives an input light at a respective wavelength and produces a corresponding collimated output light traveling from the VIPA generator in a direction determined by the wavelength of the input light, the output light thereby being spatially distiguishable from an output light produced for an input light at a different wavelength. The mirror has a cone shape, or a modified cone shape. The lens focuses the output light traveling from the VIPA generator onto the mirror so that the mirror reflects the output light. The reflected light is directed by the lens back to the VIPA generator. In this manner, the apparatus provides chromatic dispersion to the input light.

Abstract: A projection objective formed from six mirrors arranged in a light path between an object plane and an image plane is provided. The projection objective, in some examples, is characterized by having a physical distance between the vertexes of adjacent mirrors that is large enough to allow for the six mirrors to have sufficient thickness and stability properties to prevent surface deformations due to high layer tensions. In some embodiments, mirror thickness are such that surface deformations are prevented with mirrors having layer tensions lower than 350 MPa. Mirror surfaces may comprise multilayer systems of Mo/Be or Mo/Si layer pairs. In some examples, the physical distance between a vertex of the third mirror and a vertex of the sixth mirror (S3S6) satisfies the following relationship: 0.3×(a used diameter of the third mirror S3+a used diameter of the sixth mirror S6)<S3S6.

Abstract: The invention describes a system and methods for filtering electromagnetic and visual transmissions and for minimizing acoustic transmissions. Various combinations of UV, IR, and yellow-tinted filters are applied in various physical configurations to a transparent substrate such as a plastic film or glazing of a window for modifying selected wavelengths of electromagnetic radiation. For instance a light filter may have a multi-layered metallic sputtered stack having a relatively low sheet resistance. The combination of filters prevents or attenuates the passage of selected wavelengths through the substrate as needed to address security risks. The combination of filters is useful to prevent unauthorized data collection and information exchange from or within buildings or otherwise prevent such unauthorized data collection and information exchange from, for example, computer monitors or screens, personal digital assistants, and local area networks.

The mirror assembly comprises a mirror unit that is connected by a mirror arm to a support structure, e.g., a flange or bracket, that is fixed to the vehicle. The support structure projects minimally sideways of the vehicle and pivotably supports the mirror arm in a manner whereby the mirror unit and its arm can swing about a pivot axis, enabling the mirror and its arm to lie alongside a side wall of the vehicle or tightly against the rear of the vehicle. A return or rebound mechanism returns the mirror unit to its normal operational position, once contact with an obstruction that have pivoted the mirror unit from its normal position, has been removed.

Abstract: Adaptive optical elements for use in high precision lithography exposure are provided with an array of discrete actuators to provide highly stable and repeatable correction of the shape of an optical element to an accuracy of a small fraction of a very short wavelength of light in the EUV range of 1 to 50 nanometers, responsive to a metrology source and sensor arrangement. The actuators are matched to the deformation characteristics of the adaptive optical elements. Preferably, the actuators provide both positive and negative force for outward and/or inward deflection continuously over the surface of the mirror. The surface of the optical element may thus be accurately, controllably and repeatably deformed to within an allowable deformation limit to optimize optical performance of an optical system for high precision lithography exposure.

Abstract: In a method for imaging using multiple apertures, the present invention uses a wavefront sensor, a phase sensor, and an image processor to construct a high-resolution image without using complex relay optics. A wavefront sensor collects information that allows the wavefront from each aperture to be reconstructed and a phase sensor collects information regarding the relative phase difference between the apertures. An image processor uses the information collected from the phase sensor to correct the phase differences between the apertures, reconstruct the wavefronts from the wavefront sensor data, then coherently sums the wavefronts from each aperture to form a high-resolution image that corresponds to a synthesized aperture that is larger than any of the individual apertures.
