Who’s who: The quantum Alice in Wonderland would like to understand whether the many “Twindeldum-Twindeldees” she sees are really identical or not, and uses the new interferometer for this purpose.
High precision, dynamic interferometer combines short and long coherence capabilities into one system for measuring an expanded range of optics. 4D Technology, a subsidiary of Onto Innovation, ...
The gravitational wave transmits an energy packet to the light wave. It should be feasible to observe both phenomena, namely, the stimulated emission and absorption of gravitons, although this would ...
A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...
A team of astronomers from the U.S. Naval Observatory (USNO), Naval Research Laboratory (NRL) and the European Southern Observatory (ESO) have successfully used the ultra high-resolution capability of ...
The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...
Measurement-based linear optics implements a huge multi-mode interferometer consisting of beamsplitters (green) and phase delays (blue). The size of the virtual interferometer can be many hundreds or ...
THE co-ordination of laboratory and class work is usually a problem of much difficulty in physics courses above intermediate standard, so that not infrequently there is little if any attempt made in ...
