Abstract

2-D optical scanner PZT bimorph Tapered single mode fiber Electronic Optical and Magnetic Materials Condensed Matter Physics Computer Science Applications Applied Mathematics Electrical and Electronic Engineering
An image acquisition utilize a 2D piezoelectric actuated optical scanner is presented. The scanner is consisted of a chemically etched tapered single mode optical fiber (SM600) mounted on a X-Y coupled piezoelectric bimorphs operating at the actuators' resonant frequencies of 2800 Hz and 70 Hz, that generates a40 lines raster scanning light pattern around the area of interest. The image is acquired by a nearby photodetector based on the reflected intensity generated by the scanner. . The scanner achieves a 64.5 μm vertical and 7.6 μm horizontal tip displacements with a ± 18V input. Initial 1D image acquisition shows the system is capable of resolving a line pattern of 85μm with a gap space of 100μm with a S/N ratio of 10 dB. © 2013 SPIE.
