<p>An apparatus for imparting a controlled relative displacement of two parallel surfaces along a single axis or along two orthogonal axes is disclosed. Controlled displacement along any axes, orthogonal or otherwise, may be obtained by stacking appropriately oriented single-axis units. The apparatus uses a force-generating means (16, 17) and connecting beams (4, 5, 13, 14) acting in concert to produce a relative displacement of two rigid parallel frames (2, 7). An imaging means (15) is mounted on one rigid frame and a photosensitive matrix (3, 11) on the other to provide an electro-optical detector system in which the image field may be periodically displaced along a closed trajectory to cover the interstices between the detector elements of the photosensitive matrix. <IMAGE></p> |
