Compact 6-DOF Stage for Optical Adjustments

Adjustments can be made in all translational and rotational degrees of freedom. The figure depicts selected aspects of a six-degree-of-freedom (6-DOF) stage for mechanical adjustment of an optical component. The six degrees of freedom are translations along the Cartesian axes (x, y, and z) and rotations about these axes (θx, θy, and θz, respectively). Relative to prior such stages, this stage offers advantages of compactness, stability, and robustness, plus other advantages as described below.

Eye On Innovation

Dual-Use InnovationBy Dr. Udo Ungeheuer Chairman of the Board of Management SCHOTT Mainz, Germany Many people consider the printing press developed here in Mainz, Germany, near the headquarters of SCHOTT, the greatest invention of the last 1,000 years. Yet, many of the key technologies that made the development of the press possible were first developed for other, quite different applications. The screw press originally was developed to press grapes and olives for wine and olive oil. The new alloys that Gutenberg developed for moveable typeface were an outgrowth of weapons and armor metallurgy. The oil-based ink used by Gutenberg was developed for paintings, not books.

Probing a Spray Using Frequency-Analyzed Light Scattering

Intact length and breakup frequency are determined by a relatively simple technique. Frequency-analyzed laser-light scattering (FALLS) is a relatively simple technique that can be used to measure principal characteristics of a sheet of sprayed liquid as it breaks up into ligaments and then the ligaments break up into droplets. In particular, through frequency analysis of laser light scattered from a spray, it is possible to determine whether the laser- illuminated portion of the spray is in the intact-sheet region, the ligament region, or the droplet region. By logical extension, it is possible to determine the intact length from the location of the laser beam at the transition between the intact-sheet and ligament regions and to determine a breakup frequency from the results of the frequency analysis. Hence, FALLS could likely be useful both as a means of performing research on sprays in general and as a means of diagnostic sensing in diverse applications in which liquid fuels are sprayed. Sprays are also used for drying and to deposit paints and other coating materials.
