    We present a novel method for single frame particle image velocimetry of micron scale spheres based on holographic video microscopy. Our approach takes advantage of the blurring that recorded holograms suffer when a sphere moves during the exposure period of the camera. By measuring the angular variance in intensity of the blurred hologram, we extract a modelindependent metric for the particle velocity. We find this to be accurate for speeds that permit characterization of other properties of the sphere, such as radius and refractive index through Lorenz-Mie mocroscopy. Singl-frame holographic velocimetry yields information on the dynamics of a particle, without sacrificing any other measurements.
