PROF. BARUS' work is divided into twelve chapters, and occupies an intermediate position between the usual textbook dealing with routine work and the ordinary type of original research which attacks ...

Sensors for the measurement of displacement based on a number of different physical principles are available for a wide range of applications. This article considers systems capable of resolutions of ...

The following application note describes how to use the Zurich Instruments MFLI, a 500 kHz Lock-in Amplifier, for the purpose of measuring, stabilizing, and controlling the relative distance of two ...

The AIMS Interferometer represents over 20 years leading edge development resulting in easy to use, robust products, which have been specifically optimised for each measurement application. All ...

It is not an easy task to measure to the nanometer scale—achieving it requires careful engineering and a stable sensor. The sensors employed for stage position feedback within semiconductor ...

Scientists needing to make sensitive displacement measurements will benefit from a simple way to increase the resolution of an interferometer. Researchers in France have discovered a clever way to ...

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 ...
