Paper Abstract

Basic principles for interferometry with ultrashort-pulse lasers are described. Different interferometer configurations for use as sensors for optical shape and deformation measurement are discussed. The sensor configurations that are mainly treated, are: the non-scanning white-light interferometer as distance and pulse length sensor. Speckle interferometry with ultrashort pulses for three-dimensional shape measurement. Light-in-flight recording by holography for visualization of light propagation and for three-dimensional shape measurement. Digital light-in-flight recording by holography. Holographic interferometry with ultrashort pulses.
