Manufacturing a precision surface requires a balance between satisfying the optimum quality requirements at the minimum cost. Steve Martinek summarizes the challenges of increasing the precision ...

Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...

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 ...

While the E-ELT (Extremely Large Telescope – 39.3 meter mirror) and its first suite of scientific instruments are being constructed, a third generation of instruments for the Very Large Telescope ...

A new method based on optical interferometry, to monitor structural damage to buildings hit by earthquakes in real time, is the outcome of the Foresight research project, led by the Politecnico di ...

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 ...
