Course Description:
This four-hour course will introduce the novice to the operation of gratings, monochromators, and spectrometers. The course will use a minimum of mathematics, relying instead on providing the fundamental concepts essential to the successful implementation of these frequency-selective devices. The differing frequency scales (gigahertz, Angstroms, inverse centimeters, nanometers, microns, etc.) will be described and compared. The basic operation of gratings will be reviewed, including issues of blaze, holographic gratings, backlash, and resolving power. The implementation of gratings into spectrometers and monochromators will then be addressed, along with their use in practical applications. The Fabry-Perot device will next be discussed, indicating its use for laser frequency analysis. Other spectral analyzing interferometers will be discussed, including the Michelson, the Gires-Tournois, and the Fizeau.  Throughout the course, practical considerations will be emphasized.

Each idea is explained in clear and simple terms with an emphasis on underlying physical principles and with a minimum of mathematics. Pertinent references and review material are identified. The course notes contain copies of each vuegraph used during the day so that participants can spend a maximum amount of time listening and understanding.

This course will enable you to:

Intended Audience
Engineers, scientists, technicians, and managers who need a familiarity with frequency analysis of optical signals, grating spectrometer devices, and other spectroscopic techniques.
