Optical Temperature Measurement

Course Description

Optical temperature measurement is a valuable tool to obtain temperature data in a reliable and efficient manner. Product development and in-service product problem analyses typically require reliable detailed testing. Test costs in terms of dollars and schedule can greatly affect the company’s financial bottom line. Of even more importance, misleading data can seriously affect product reliability and the company’s reputation. This course addresses the benefits and potential pitfalls of obtaining temperature data using optical instrumentation systems.

Objectives

The objectives of thismeasurement course are to:

• enable instrumentation engineers to evaluate optical temperature measurement systems, to select the most appropriate system for an application or specify a new system where required.
• enable test technicians to better understand how to properly apply this technology.
• help the data customer understand how radiation based temperature measurements are made and the possible limitations in interpreting the resulting data.

To achieve these objectives, the course proceeds as follows:

• A brief survey of typical optical temperature measurement applications is presented.
• A history of the development of optical temperature measurement, accompanied by descriptions of the various concepts involved: the basics of thermal radiation, the concept of the blackbody, spectral characteristics of blackbody radiation, and how real surfaces deviate for a blackbody.
• A description of the basic components of radiation pyrometers (point measurement systems): detectors, optical components, and signal conditioning.
• Guidelines for selecting a pyrometer system, based on: cost, accuracy, temperature range and frequency response.
• Line scanning systems, Thermography systems.
• Pyrometer calibration.
• System demonstrations.
• Miscellaneous “optical temperature measurement” topics, often associated with “optical temperature measurement” complete the course:

• Temperature indicating labels and paints, and liquids crystals
• Fiber optic thermometers
• Coherent Anti-Stokes Raman Spectroscopy

Where and When

• The course is taught for 8 hours in a classroom.
• Note: You must attend all 8 hours to complete the course.
