    Abstract: A micromechanical device including an improved sensing element and improved bending elements is described. Sensing elements include multi-layered structures which are thinner, lighter, and flatter than structures presently known within the related arts. Bending elements include structures which separately respond to illumination by an infrared source so as to twist a sensing element. Micromechanical pixels may be arranged to form two-dimensional arrays of infrared sensitive pixels. Arrays of micromechanical pixels are applicable to imaging devices for use within the fields of security and surveillance, firefighting, automotive safety, and industrial monitoring.

    Abstract: A method for reducing the noise equivalent temperature difference associated with imaging devices having a detection array including micro-cantilevers and a charged-coupled device or a complementary metal oxide semiconductor imager is presented. The method includes calculating horizontal and vertical pixel ratios based upon the number of receptor pixels and micro-cantilever pixels, defining composite pseudo-pixels comprised of at least two receptor pixels, capturing at least one frame of an image, calculating the composite intensity for each composite pseudo-pixel based on the intensities of the receptor pixels therein, and reconstructing each frame so that receptor pixels within each composite pseudo-pixel are displayed with the appropriate composite intensity. While the present method lowers pixel resolution, the composite pseudo-pixels maintain image resolution within the reconstructed image.
