The Phase Doppler Interferometer (PDI) is an in situ airborne interferometer developed by Artium Technologies, Inc. It uses light-scattering interferometry and laser Doppler velocimetry to measure the size and velocity of spherical cloud particles. It operates at wavelengths of 491, 532, 561, and 660 nm and has a measurement duration of 1 second. PDI can measure droplet sizes from 0.3 to 6000 μm and velocities from -600 to 1000 meters per second.
