Sophisticated Signal Processing for LDV and PDPA Measurements - Determining Particle Velocity and Size

Laser Doppler Velocimetry (LDV) and Phase Doppler Particle Analysis (PDPA) are techniques in which optical signals scattered from particles are analyzed in order to determine the velocity and diameter. The signal processing for these types of measurements is quite sophisticated.

In this 30-minutes webinar, we will be examining the internal processing techniques and principles used in the new Flow Size Analyzers FSA 4800/5800 for LDV and PDPA. We will be also discussing new developments in high-frequency signal processing and conclude the webinar by showing some sample data.
