In this work, we demonstrate the simple fabrication process of AlN-based piezoelectric energy harvesters (PEH), which are made of cantilevers consisting of a multilayer ion beam-assisted deposition. The preferentially (001) orientated AlN thin films

In this contribution we focus on laser frequency noise properties and their influence on the interferometric displacement measurements. A setup for measurement of laser frequency noise is proposed and tested together with simultaneous measurement of

We present an interferometric technique based on a differential interferometry setup for measurement under atmospheric conditions. The key limiting factor in any interferometric dimensional measurement are fluctuations of the refractive index of air

We report on an instrument for calibration of the 8-mm length gauges, currently being developed and finalised at ISI. The design and construction were focused on elimination and compensation of the typical error sources associated with laser interfer

We compare three focus sensors designed for the optical topography measurement of rough surface specimens with submicron accuracy. The laser beam was modulated by three specific computer-generated holograms displayed on a spatial light modulator.

Besides the environmental fluctuations, the typical sources of significant uncertainty in the laser interferometry systems are the geometrical errors. These are stemming, among others, from the misalignment of measurement axes, the thermo-mechanical
