Fiber optic sensors in the laser optical engineering technology laboratories at the Oregon Institute of Technology

Optical fibers are finding increasing application in feedback and control systems, medical, industrial, illumination and imaging applications, discrete, as well as distributed sensors and networks. In addition to a course in optical fiber principles and components, a fiber optic systems and applications course designed for both electronics and optical engineering technology students has been created at the Oregon Institute of Technology, in the Laser Optical Engineering Technology (LOET) Department. The systems and applications course is designed to illustrate the benefits of using fibers in communications and sensing, as well as to provide hands-on exposure to concepts of test, measurement, and calibration of fiber-optic components and instrumentation. In the laboratories of both courses, optical fiber sensor experiments are used to teach such concepts as selection and testing of components, design and assembly of transducers, system integration, testing, characterization, and optimization. These two mandatory courses provide an excellent introduction to optical fiber technology and applications. The courses exist primarily due to an NSF-OIT grant, however, companies have made significant contributions of hardware to the program. As a result, over $350 K of fiber optics components and instrumentation now are available for senior-students' use, to develop unique, year-long projects.
