Abstract: A beam multiplier includes a beam-multiplying layer and an adjacent optical layer. The beam-multiplying layer is operable to generate output beamlets of light from an input beam of light, and the optical layer has an adjustable index of refraction. By switching the index of refraction of the optical layer between first and second values, one can switch the beam multiplier to a first state (e.g., “on”) where it generates the output beamlets of light, and can switch the beam multiplier to a second state (e.g., “off”) where it passes the input beam of light but does not generate the output beamlets. And by using the beam multiplier as an exit-pupil expander, one can switch the exit-pupil expander to a first state where it generates multiple exit-pupil images, and to a second state where it generates only a single exit-pupil image.

Abstract: Disclosed herein is a method of precisely correcting geometrically distorted satellite images. In order to correct a geometrically distorted satellite image, the position and attitude of a satellite must be accurately recognized. In this case, a correlation between the position and attitude values of the satellite exists, so accurate position and attitude values cannot be obtained. Therefore, the present invention accurately obtains position and attitude information of the satellite by separating variables having a high correlation to minimize the correlation between the position and attitude of the satellite and then calculating corresponding variables, and precisely corrects a geometrically distorted satellite image using the position and attitude information of the satellite.
