This continuing education course is written specifically for professional engineers with the objective of relating to and enhancing the practice of engineering.
This course provides an introduction to displacement measuring interferometry, which offers high accuracy, range, and resolution for non-contact displacement measurement applications. The heterodyne (or two frequency) Michelson-type interferometer is described. Additionally, a brief review of the fundamentals of light theory, polarization, and interference is provided. Graphical descriptions are included to complement the text. Examples include figures that reinforce concepts in polarization, identify components in displacement measuring interferometers, and detail the function of fiber optics in interferometry. Upon completion of this course, the engineer should possess the basic knowledge required to select and implement displacement measuring interferometry in the desired application.
