Here are some books I've found useful during my PhD. They cover mechanical vibrations, laser vibrometry, and modal analysis.
A thorough introduction to modal analysis theory and practice, including experimental and operational modal analysis techniques.
Collection of expository articles that explain modal analysis concepts in a clear, intuitive manner โ great for building understanding.
Practical guide to modal testing procedures, from setup and data acquisition to parameter estimation and validation.
Application note that explains key signal analysis concepts โ sampling, aliasing, FFT, windowing โ essential for experimental work.
Balanced approach between theory and real-world applications, with worked examples and MATLAB exercises.
