temperatures far beyond this could be reached [9, 101, and there has even been speculations that nuclear fusion could be obtained by sonoluminescence [ll, 12]! In this article we 1 FrrsWnw demonstrate experimentally that this is very improbable.

AbstractWe have performed an experiment on sonoluminescence in liquid heavy water. We have vefied that sonoluminescence takes place with air bubbles as well as with D, bubbles in heavy water (98.5% D,O). No radioactivity originating from the phenomenon has been observed.
New liquid-crystal media and photoconductor materials are being utilized in spatial light modulators to increase their resolution, diffraction efficiency, speed, and sensitivity. A prototypical device developed for real-time holography applications has shown an 8% diffraction efficiency from a holographic grating with a spatial frequency of 370 line pairs/mm (lp/mm). At 18 lp/mm the device has demonstrated a 31% diffraction efficiency with a 600-micros hologram write time using 400-nJ/cm(2) write beams.
SLarge numerical aperture telescope with nonlinear optical correction for distortions, designed for the remote seff-luminous object imaging, was realized in experiment and investigated. Dynamic hologram, recorded in optically addressed liquid crystal spatial light modulator, was used as the corrector. Nearly diffraction limited performance of the system was demonstrated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
