title: Light-in-flight recording. 6: Experiment with view-time expansion using a skew reference wave.
abstract: In normal light-in-flight holography the largest time difference that can be created in the image is when the reference light falls nearly parallel with the photographic plate. In that case, where the pulse front is perpendicular to the direction of propagation, the time scale on the plate is given by the speed of light. Thus the time it takes for the reference light to go from one side of the plate to the other sets the upper limit of the observable time interval. By using a reference light where the pulse front is leaning backward, this view time can be increased several times.
