    摘要: Small, rugged scanners micro-fabricated from commercial optical fibers to form waveguides or other structures. The scanning waveguide has a distal portion on which is formed a non-linear taper with a diameter that decreases toward a distal end. Optionally, a hinge portion having a reduced diameter can be formed in the distal portion, improving the scanning properties of the waveguide. A micro-lens can be integrally formed at the distal tip of the waveguide with either a droplet of an optical adhesive, or by using an energy beam to melt the material of the waveguide to form a droplet. The droplet is shaped with an externally applied force. When mechanically driven in vibratory resonance, the tip of the optical waveguides moves in linear or two-dimensional scan patterns of relatively high amplitude and frequency, and large field of view. The scanner can be used either for image acquisition or image display.
