The technique for creating these was invented in 1947 during Dennis Gabor's efforts at improving the resolution of electron microscope images. They can be used to study elastic deformation effects as well as tiny mechanical variations. They are recorded by shining a laser beam on an object and recording the scattered and reflected light along with a reference beam to obtain phase information. When the process is reversed, the recorded interference fringes act like a diffraction grating and produce a real image with more information than a standard photo.

When the process is reversed, the recorded interference fringes act like a diffraction grating and produce a real image with more information than a standard photo. With a name derived from the Greek words for "complete" and "message," FTP name these advanced photographs that allow the storage of three-dimensional information.
