A moving platform roll sensor system comprises an ellipsometric detector capable of detecting a polarized beam within the detector's line-of-sight, and measuring the beam's polarization state, such that the polarization state indicates the rotational orientation of the moving platform with respect to a predefined coordinate system. The ellipsometric detector comprises a venetian blind component through which the polarized beam passes, arranged such that the intensity of the exiting beam varies with its incident angle with respect to the moving platform, a polarizing beamsplitter which splits the exiting beam into components having orthogonal circular polarizations, the relative intensities of which vary with the relative polarization vector of the beam, and first and second detectors which receive the first and second orthogonal circular components and generate respective outputs that vary with the intensities of their received components. The beamsplitter preferably comprises a quarter wave plate and a polarization grating.

An optical tracking system comprises an array of point source emitters that output respective optical emissions, and a plurality of angle of arrival sensors. Each sensor comprises one or more optical elements and a focal plane array (FPA), with the optical elements arranged to resolve the optical emissions into one or more linear patterns on the FPA. A processing system in communication with the sensors establishes the orientation and position of each of the optical emitters using the linear patterns. A headgear tracking system employs point source emitters on a piece of headgear, with front and rear arrays of angle of arrival sensors located in an aircraft cockpit; a processing system in communication with the sensor arrays establishes an orientation and position for each of the optical emitters on the headgear.

A fast, electro-optically switched zoom lens system operates across a broad spectral and thermal range while correcting for birefringent aberrations by means of a polarizing system that preferably includes polarizing reticles.

An optical fiber coupling, for example, an optical switch, for coupling a light source with a light-receiving end face of an optical waveguide comprises a lens for focusing a light beam emitted from the light source at a focal point on the light-receiving end face of the optical waveguide. An adaptive coupler positioned in the optical path is responsive to a beam steering control signal for steering and aligning the focal point relative to the light-receiving end face of the optical waveguide.

Apparatus for optically coupling a light source with an optical waveguide

An apparatus for optically coupling a light source with a light-receiving end face of an optical waveguide comprises a lens for focusing a light beam emitted from the light source at a focal point on the light-receiving end face of the optical waveguide. An adaptive coupler, positioned in the optical path, is responsive to a beam steering control signal for steering and aligning the focal point relative to the light-receiving end face of the optical waveguide. In one form, the adaptive coupler comprises a pair of transparent substrates having confronting, parallel inner faces, the inner face of one of the pair of substrates carrying a beam intercepting, optically transparent, constant potential electrode and the inner face of the other of the pair of substrates carrying an electrically resistive, beam intercepting, optically transparent film. A pair of spaced apart electrodes in electrical contact with the film apply a linear voltage gradient along the film. An electro-optical phase shifting medium is disposed between the confronting inner faces of the substrates. The application of selected voltages to the electrodes creates a linear voltage gradient along the aforementioned film on the inner face of the one substrate resulting in a linearly varying electric field between that film and the constant potential electrode creating a corresponding linear variation in the refractive index of the liquid crystal medium and a linear wavefront tilt in the intercepting optical beam.

A liquid crystal cell in which the electrodes are patterned with small scale non-conducting gaps so as to efficiently control the number, size and location of liquid crystal domains within which the liquid crystal exhibits an azimuthal orientation with predominantly the same sign and direction in a field-on condition. By patterning one or both of the electrodes with small scale non-conducting gaps, having widths less than about 2.5 times the cell gap t, that are disposed predominantly within the liquid crystal domains, or a combination of such gaps with gaps disposed primarily along the domain boundaries, one not only can obtain excellent control of the nature of the liquid crystal domains, but also the responsiveness of the cell.
