Short courses in radiometry and allied topics

available from

Dr. James M. Palmer

A number of short courses on radiometric topics have been developed primarily for SPIE- The International Optical Engineering Society, the Optical Society of America, and Optical Science and Engineering Short Courses, Inc. They include:


Custom courses

Customized short courses, largely based upon those listed above, have been prepared and presented in several formats to the following organizations:


VIDEO COURSE

A 5-hour video course entitled "Fundamentals of Radiometry: Calculations, Measurements and Calibration" was prepared for SPIE and aired on the NTU satellite television network.  It is  available for purchase directly from SPIE.


CD-ROM COURSE

The video course entitled "Fundamentals of Radiometry: Calculations, Measurements and Calibration" is currently being reformatted for CD-ROM presentation. It will include both the audio and video portions of the taped course, and will also include quizzes (with answers) and a glossary. It will be  available for purchase directly from SPIE.

Course length: Half day

Intended audience: The course will be helpful to engineers and technicians who are required to design and test radiometric systems and make radiometric measurements and calibrations.

Course description: The core of radiometry is the geometrical transfer of radiant energy from point A (the source) to point B (the receiver). It is necessarily mathematical in nature, but the task can be simplified through the use of reasonable approximations. This course deals with the methods of determining the propagation of optical radiant energy through simple and complex optical systems.

Intended audience: The course will be useful to those engineers and technicians who are required to purchase or design and build radiant energy sources for radiometric systems and calibration.

Course description: Radiant energy is generated by all matter at temperatures above 0K. This radiation can be considered a signal (desirable) or a noise (unwanted). A solid understanding of the characteristics of thermal radiation is essential to the design of infrared and radiometric instruments and systems. This course covers all of the essentials of thermal radiation sources, both artificial and natural, and includes luminescent sources for the visible and infrared as well.

Course length: Full day  (half-day available for T&P) 

Intended audience: The course will be helpful to those engineers and technicians who are required to purchase or design and build radiometric systems and use them for radiometric measurements.

Course description: Radiometric instruments generate an output signal in response to optical radiant exchange with their surroundings. Calibration is the process of quantifying this signal in terms of radiometric units (e.g., watts). This course not only answers the question "Why calibrate?" but details current calibration methods and standards. The latest methods of bandwidth and field-of-view normalization are included along with a discussion of calibration error sources. Examples of real situations will be given.

Course contents:

Responsivity calibration methods
Spectroradiometric calibration
Bandwidth normalization

Radiometric measurements are among the most difficult to make, principally because of the number of variables involved and the wide range of measurement parameters.

The selection of a detector for inclusion in a radiometric system involves more than just picking one out of a catalog. To ensure a successful design, the engineer must consider the optical, thermal, mechanical and electronic interfaces between the detector and its immediate environment.
