Phase Doppler Interferometer (PDI)

PDI Theory of Operation
 
 

Artium's PDI system consists of an optical transmitter, optical receiver, signal processor (ASA), the instrument control computer, and the software (AIMS). Artium offers a variety of optical designs to meet different spray applications. Systems capable of measuring droplet size and 1-, 2-, or 3-components of velocity are available either in a modular or self-contained design configurations. The laser wavelengths and power can be customized based on the application and user needs. A flight probe design is available for in-flight applications such as cloud characterization or aircraft icing research. The standard flight probe is a capable of measuring size and a single component of velocity. A dual-size range flight probe is also available.
