Phase Shifting Interferometry

Famous quotes containing the words phase and/or shifting:

    The Indians feel that each stage is crucial and that the child should be allowed to dwell in each for the appropriate period of time so that every aspect of his being can evolve, just as a plant evolves in the proper time and sequence of the seasons. Otherwise, the child never has a chance to master himself in any one phase of his life.
    Alan Quetone (20th century)

    How strange a scene is this in which we are such shifting figures, pictures, shadows. The mystery of our existence—I have no faith in any attempted explanation of it. It is all a dark, unfathomed profound.
    Rutherford Birchard Hayes (1822–1893)
