Abstract: A lenticular print and method of producing that substantially reduces progressive pixel misalignment to produce a lenticular print that has increased angular resolution. The lenticular print includes a dot matrix pixel arrangement that is rotated with respect to the X-Y axis of a printer. The printed output of the rotated dot matrix pixel arrangement requires substantially no re-sampling interpolation. The lenticular print includes a conventional lenticular sheet having a plurality of convex shaped lenticular elements wherein the axis of the lenticular elements are substantially aligned with the axis of the pixel direction.

Abstract: The DTF optical memory makes use of the property of dielectric thin film interference to create multi-color pixels and serve as a multi-level optical memory device. The fabrication of the device comprises a dielectric thin film deposited on a substrate that is micro-milled utilizing focused ion beam (FIB) technology. Such micro-milling creates pixels of varying depth that when exposed to a broad-band light source create distinct colors caused by the properties of thin film interference and superposition of reflected light from the broad band source, thus creating an effective optical memory device that may be detected using a color CCD camera or a photo-detector array. Accurate creation and detection of discrete colors allows accurate digital encoding and direct storage of color image in a format of sub-micron pixel array. The robustness of the DTF optical memory device allows operation under harsh environmental conditions, including high temperatures and radiation.

Abstract: A method of finding drive values for an actuation mechanism having three degrees of freedom is provided, that will optimize a predetermined parameter of a system that utilizes the actuation mechanism. In one embodiment, a method of finding drive values for a tunable Fabry-Perot cavity is provided, for driving three independently adjustable actuators such that the cavity mirrors of the tunable Fabry-Perot cavity are maintained in a substantially parallel relationship.
