摘要

A microdisplay system based on an optical fiber driven by a 2-D piezoelectric actuator is presented. An optical fiber is extended from the free end of a 2-D piezoelectric actuator (free length 4.3 mm). A field programmable gate array (FPGA) drives the actuator using a triangular waveform to deflect the optical fiber in orthogonal directions. The FPGA also controls a LED light source, and the light is coupled into a chemically tapered single-mode fiber (SMF-28, core diameter 10μm). At a preset pairing of near-resonance frequencies (horizontal 22 Hz, vertical 5070 Hz), the deflected optical fiber in combination with controlled light produces an output image with an approximate dimension of 0.1 ×0.1 mm~2, and a potential resolution of 400 lines per scan. This work details the design and fabrication of the microdisplay system. The mechanical and optical design for the microresonating scanner is discussed. In addition, the mechanical and optical performance and the resulting output of the 2-D scanner is presented.
