Electronics laboratory

The Electronics Research Laboratory specializes in electronics and computerized measurement methods employing combined modalities (e.g. ultrasonics and radiation). The main emphasis is to develop quantitative methods suitable for the needs of the industry. To support these goals, our research work concentrates on several applied physics disciplines, the main areas being ultrasonics, photoacoustics, fibre optics and confocal microscopy.

We use sound and light both to sense and to actuate across a broad spectrum of disciplines employing samples ranging from red hot steel to smooth muscle fibers. We are particularly interested in exploiting the link between the structure and mechanics of our samples.

We build and buy instruments: stroboscopic white light interferometer to characterize MEMS mechanics, Schlieren setup to detect ultrasonic fields in solids, optical tweezers to determine piconewton forces on nanometer scale (DNA,RNA), and advanced ultrasonic instrumentation for linear and nonlinear measurements in 10kHz to 100MHz frequency range both contacting and noncontacting. We also do advanced microcontroller and FPGA real-time feedback control.
