Research on resonance of fiber nutation

The cantilever optical fiber nutation structure is designed by using piezoelectric ceramic tube. The amplitude-frequency response of the structure is measured by micro-Doppler method, and the resonance characteristics are analyzed. When the optical fiber nutation structure works under resonance, the nutation amplitude is the largest. The expansion of field of view angle has the advantages of simple structure, stable and reliable performance, easy integration, and higher coupling efficiency from spatial light to optical fiber.
