Photonix Imaging's breakthrough "Light Valve"
hologram origination process forever alters the way holograms are
produced.
This process, capable of up to 2’ square high-resolution holograms,
represents significant holography industry breakthroughs in time, quality,
cost and technique. Until now, conventional
holographic production methods included use of LCD panels. Severely
limited by size, resolution, and the contrast ratio of LCD technology,
this process resulted in holograms with the
familiar fish scale patina. Other methods such as indirect transfer of the
data to motion picture film impede client input, are costly and
time-consuming. PI’s patented process addresses
these former barriers.
High resolution 50 cm x 60 cm holographic masters can now be produced in less than 2 hours from any digital source. These images have incredible detail, contrast and brightness. Color separations are automatic, registration is absolute, size, content and color corrections are made on the fly. Clients now have artistic and interactive freedom to provide input. Convergence is driving an ever increasing demand for complex data comprehension. Inexpensive holographic hard copies can help to meet that demand. The holographic printer technology is comprised of a Spatial Light Modulator, or Light Valve, and specialized optics. It uses a powerful krypton laser as its light source. This 'Light Valve printer' provides the direct link from all forms of digital graphics to holography.
