Films like "Across the Sea of Time" (1995) and "Wings of Courage" (1995) used a complex and expensive technology, based on liquid crystal "shutter" lenses, to produce strikingly sharp and bright stereoscopic images.
It settled on an idea based on liquid crystals.
Such devices are based on liquid crystals, materials that have a structure somewhere between that of a highly ordered solid and liquid where the molecules are disordered.
Dec/hyd ratios were determined based on liquid phase composition.
The autofocusing system is based on a liquid lens with less moving parts and fast response time, which makes the system simple, reliable, compact and fast.
But scientists at Philips' research center in Eindhoven, the Netherlands, say the answer may lie with lenses based on liquids rather than glass or plastic.
The NGMN method was based on liquid-liquid extraction followed by HPLC-MS/MS analysis.
Steroid determinations were based on liquid-liquid extractions and on solid-phase extractions with commercially available cartridges.
Sample preparation was based on simple liquid-liquid extraction into cyclohexane (1 : 1).
Polynomial lenses, based on tri-curve lens fittings, did not provide better initial comfort than tri-curve lenses.
