IT has been suggested to me that the accompanying photographs (Fig. 1) showing the Fabry-Perot patterns of the red Balmer line for ordinary hydrogen and for a mixture containing an appreciable amount ...

We suspect there are three kinds of people in the world. People who have access to a Michelson Interferometer and are glad, those who don’t have one and don’t know what one is, and a ...

According to Fermilab, the interferometer will occupy a 328 feet shaft at its facilities. This was used years ago for access ...

Shearography and Digital Speckle Pattern Interferometry (DSPI) are advanced optical techniques that have emerged as critical tools in non-destructive testing (NDT). Both methods utilise coherent laser ...

Matter has the mind-boggling ability to behave like waves as well as particles but it has taken physicists some time to exploit this effect. In recent years, however, various groups around the world ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies required. The authors of a new, non-peer reviewed study detail how the a ...

Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Building blocks: University of Nottingham researchers have developed a fully functional LEGO interferometer kit (courtesy: University of Nottingham) Working with “student LEGO enthusiasts”, they have ...
