Abstract: A fiber optic sensor for detecting acceleration or displacement includes a fiber optic probe with a multimode transmitting optical fiber, a multimode receiving optical fiber and a edge reflector spaced apart from the fiber probe. The reflector moves in a transverse direction substantially normal to the longitudinal axis of the fiber optic probe, so the amount of light received by the receiving fiber indicates a relative acceleration or a relative displacement of the reflective surface with respect to the fiber probe in the transverse direction of motion of the edge of the reflector. The reflector can be mounted on a cantilever beam. The sensor can have one transmitting fiber, two receiving fiber, and a reflector with two edges, each edge partially covering one of the receiving fibers. A triaxial sensor system has at least two two-fiber sensors.

Abstract: A method and system for efficiently converting an image from a first map projection to a second map projection image. The method includes precomputing coordinates in the first map projection for a subset of the total number of pixels in an empty second map projection image and subsequently, finding the first map projection coordinates of each of the remaining pixels by linear interpolation using the precomputed first map projection coordinates of the nearest surrounding precomputed pixels. A color is assigned to the second map projection image pixel with bilinear interpolation using color values of surrounding first map projection pixels. If the first map projection has fiducials, only the area within the fiducials is considered. An embodiment converts a USGS DOQ in UTM format into Geodetic coordinates.

Abstract: A method for exploiting the nonlinear structure of hyperspectral imagery employs a manifold coordinate system that preserves geodesic distances in the high-dimensional hyperspectral data space. Data representing physical parameters such as a scene is divided into a set of smaller tiles. The manifolds derived from the individual tiles are then aligned and stitched together to complete the scene. Coordinates are derived for a very large although not complete representative subset of the data termed the “backbone”. Manifold coordinates are derived for this representative backbone and then the remaining samples inserted into the backbone using a reconstruction principle using the property of local linearity everywhere on the manifold to reconstruct the manifold coordinates for the samples not originally belonging to the backbone. The output is a global manifold coordinate system, which for topographical image data depicts clearer detail of land and water portions of a scene.
