Particle image velocimetry (PIV) allows measuring distributed flow velocity fields. It is well established as an experimental tool in modern fluid dynamics research, being applied to liquid, gases and multiphase flows. Images of tracer particles are

This article proposes an analytical algorithm for predicting errors in lock-in amplifiers (LIAs) working with time-varying reference frequency. Furthermore, a simple method for correcting such errors is presented. The reference frequency can be swept

A phase locked loop (PLL) based on digital signal processing and random sampling is proposed in this paper. Field programmable gate array (FPGA) technology is used to implement a prototype. The random sampling scheme is used to reduce the sampling fr

A high-performance digital lock-in amplifier implemented in a low-cost digital signal processor (DSP) board is described. This lock in is capable of measuring simultaneously multiple frequencies that change in time as frequency sweeps (chirps). The u
