Optical Measurement Techniques in Thermal Sciences

In thermal and fluid sciences, capturing accurate data without disturbing the system is a constant challenge. This text-based course introduces you to the principles and applications of optical measurement techniques, allowing you to analyze temperature fields, concentration gradients, and flow velocities non-intrusively. You will transition from understanding basic light behavior to interpreting complex optical data. What you'll learn: Understand the foundational principles of wave optics, refraction, and light-fluid interactions; Analyze temperature and density fields using interferometry and shadowgraphy; Measure fluid velocities using laser-based diagnostic techniques; Apply digital image processing fundamentals to extract quantitative data from optical patterns; Evaluate experimental errors and calibrate optical setups for thermal analysis. The course begins with essential terminology, wave optics theory, and the physical principles of light propagation through varying refractive indices. You will then progress through specific experimental setups, image analysis techniques, and modern digital reconstruction methods used in research and industry today. This course is designed for engineering students, researchers, and practicing thermal analysts who are new to optical diagnostics and want to build a solid theoretical and practical foundation.
