Rotational Doppler velocimetry to probe the angular velocity of spinning microparticles [PDF]

, 2014
Laser Doppler velocimetry is a technique used to measure linear velocity, ranging from that of exhaust gases to blood flow. A rotational analog of laser Doppler velocimetry was recently demonstrated, using a rotationally symmetric interference pattern to
