Abstract
In this paper we present results of our interferometric system for embedded optical fiber in composite material, where a laser diode is used as light source. Optical phase changes induced by laser diode injection current modulation are characterized in order to apply an optoelectronic setup for stabilization and optical phase modulation. He-Ne source versus laser diode are compared for the system. Details on parameter characterization, specially visibility drift and environmental disturbance impact, are analyzed. Experimental design and the results observed are also given.
