Paper Abstract

Albert Einstein has in his memoires written that he as a young boy pondered about what a light wave would look like to an observer riding along with it. One hundred years after his birth in 1879 it has now become possible to make observations that to a surprisingly high degree correspond to that proposed method. A flat object surface and a hologram plate are both illuminated at an oblique angle by laser light of short pulse duration or short coherence length. Only those parts of the object surface are holographically recorded that correspond to small pathlength differences between object beam and reference beam. The hologram plate therefore corresponds to an infinite set of gated viewing systems triggered by the traversing reference beam. Scanning along the processed plate produces a continuous motion picture of the light in flight.
