Researcher Describes the Invention of Holographic Interferometry
Holographic interferometry is a method for using light to measure stress, strain, and vibration. It determines defects in structural bonds by measuring the light’s wavelength. It fully utilizes a hologram’s capacity to mimic an object’s optical field of reflection or transmission.
