Abstract
Disclosed are a vectorial rotation velocity measurement method and device based on multi-core fiber, which belongs to the field of optical measurement. Input multiple lights are transmitted through a non-uniformly distributed space to form a structured non-uniform spatially-distributed scalar light field, wherein the scalar light field serves as a collimated probe light to illuminate rotationally moving particles, the rotationally moving particles reflect a signal light carrying motion information, the signal light is subjected to a Fourier analysis to obtain a Fourier amplitude spectrum and a Fourier phase spectrum, a velocity of the rotationally moving particles is calculated through a frequency peak in the Fourier amplitude spectrum, and a direction of the velocity of the rotationally moving particles is calculated using a relative phase difference value corresponding to the Fourier phase spectrum, thereby realizing a measurement of vectorial rotationally moving particles based on the multi-core fiber.
