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 ...

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

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 ...

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 ...

A lot of what I write is about measurement, not because I'm in love with calipers, but because the cutting edge of physics is at the limit of what we can measure. That means that when you want to ...

This article outlines how to measure, control, and stabilize the relative distance of two interferometer paths to sub-wavelength precision over numerous wavelengths, using the Zurich Instruments MFLI ...

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 ...
