Software-based processing system for phase Doppler systems

A Monte Carlo simulation of Phase Doppler systems has been developed. It consists three sections, the droplet flow description, generation photomultiplier signals and then their processing to determine velocities time shift between from scattered light detection apertures. With highly realistic bursts being simulated processed, question arises as whether signal software could be used process ‘real-world’ experimental signals. In a preliminary assessment its capabilities in such situation, actual spray (from Dantec fibre-based PDA system with BSA processor) were recorded input processor. The photomultipliers first into Picoscope this way size estimates would available control data. outputs taken csv files, directly Initially determined location centre each burst envelop. This approach was shown measure delays single cycle multiple cycles. For experiment, modified by adding zero-crossing delays. introduction method should establish accuracy complete package real world results experiment show good agreement two techniques.
