Methods of hologram interferometry are used to study load-deflection characteristics of small components. More specifically, fundamentals of the methods of double-exposure hologram interferometry, time average hologram interferometry, and heterodyne hologram interometry are discussed, procedures for quantitative interpretation of holograms are outlined, and their applications are illustrated by representative examples. Results presented in this paper indicate viability of the methods of hologram interferometry for quantitative studies of small components.
