Double-shot 3-D displacement field measurement using hyperspectral interferometry ReicholdTobias RuizPablo HuntleyJonathan M. 2019 A combination of a Michelson interferometer, a micro-optic element and a hyperspectral imager is used with broadband illumination to measure depth-resolved out-of-plane displacements without any scanning. Reference and deformed states of a transparent sample are recorded in single shots and used to evaluate the displacement field at different interfaces.
