  • Desktop autostereoscopic display using compact LED projector
    ...point of the screen at the viewing area and allows the screen size to be made larger . Because the corner reflective mirror sheet and the anisotropic diffuser sheet are made of flexible plastic , the curved shape can be easily constructed by using a concave base.
  • Display holography for medical tomography
    ...as a sheet of aluminum-coated plastic stretched across the mouth of a large loudspeaker, a "woofer". The woofer is driven with a deep pure tone so that the plastic sheet oscillates back and forth between convex and concave . This acts as a mirror with a rapidly oscillating focal length, and anything seen in the mirror...

  • A three-colour quantitative schlieren system
    ...each slice did not seriously affect the colours in the schlieren photographs, although large errors degraded the... A concave mirror produces a collimated beam which passes through the plastic walls of the gallery and is reflected back by the plane mirror.
  • Checking the symmetry of stretchable plastic membrane concave mirrors using a lateral shearing interferometer
    The circular stretchable plastic membrane mirror for optical purposes was first described in 198 by one of the authors, Reference 1 . The then very optically imperfect concave mirror was used as a large diameter light collimator in a flow visualiser.

    In 1961 Muirhead reported on a very simple design for varifocal mirrors with large variability of focal length [MLirhead 61]. His mirror design consists of a metalized plastic film stretched over a rigid frame with an airtight... When suction is applied to the cavity, the mirror flexes back, acting as a concave spherical mirror.
  • Photonics and laser optical diagnostics for investigations of high-speed transient processes
    Suitable delays between these pulses with respect to each other are achieved by the use of a concave Mo/Si- mirror which focuses both beams for interaction with Ne-atoms into a second chamber. ...beams for impinging on the outer, respectively inner part of the focusing mirror is real- ized by using a diaphragm and a Zr-filter (only transparent in the XUV), attached in the centre of a larger diameter plastic pellicle which itself is...
  • Compact polarising Soller guides for cold neutrons
    ...mean that neutrons can only emerge from the guide at smaller solid angles near the concave surface. Equation (8) summarises the requirements for extending the totally reflecting Soller guide concept to lower characteristic wavelengths, i.e. the need for smaller channel widths, larger radii of curvature and larger effective coherent scattering densities for the mirror material. . ...neutron beams produced by reflection from CojoFejo thin films deposited on to various plastic substrates (Penfold et...
  • Progress toward large-aperture membrane mirrors
    ...there is a vastly superior thickness uniformity of the CP-1 material (over the polyethylene plastic Tap). We recently completed the design and fabrication of a larger membrane mounting apparatus. which accommodates a 71... This membrane mounting structure allows for testing of candidate membrane materials as flats, or as concave mirrors down to — f3.
