Abstract

This paper details the improvement of image quality of the previously developed piezoelectric driven 2D Optical Display system using an optical fiber waveguide. The current display system is able to produce a desired image (FPGA input) via the oscillation of a micro-fabricated cantilever waveguide or an optical fiber "pixel" driven by two piezoelectric actuators in perpendicular arrangements; however, the image produced is blurred and unstable. To sharpen the image and allow a more detailed image to be displayed, a more refined output "pixel" is needed. To obtain such a "pixel", optical fibers with a tapered tip and metallic deposits is to be used on the output end. The use of the tapered fiber as a waveguide reduces the light that was being misguided by the cladding of the fiber and produces a finer "pixel" at each point of the image, reducing the blurriness of the displayed image. A closed loop feedback control was also added because the existing system requires manual frequency calibration to find the proper frequency to display the image after each system reset. The added control will find the proper frequency by matching the input image and the output image via image recognition coding in MATLAB and adjust the system to the optimal display frequency at the initialization of the system.
