Abstract

This chapter presents operation principle, configuration, and basic properties of instrumentation often used in the measurement and characterization of fiber-optic devices and systems. The purpose of this chapter is to set up a foundation for basic understanding of optical measurement mechanisms, methodologies, and their theoretical background. The instruments discussed in this chapter include optical spectrum analyzers; scanning Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac loop interferometers, wavelength meters, and optical ring resonators; polarization properties of optical signal and optical polarimeters; optical measurement techniques based on coherent detection; high-speed optical waveform measurement techniques with analog and digital oscilloscopes, optical sampling, and optical autocorrelation; and LIDAR, OCT, and optical network analyzers.
