title: Quantitative phase analysis in electron holographic interferometry.
abstract: Holographic interferometry in an electron microscope and its phase analysis technique are described. The fringe scanning method is used to gain high sensitivity in phase detection. An example of measuring a magnetic field of a fine particle is presented. The measurement accuracy for median filtering is about 1/70 fringe corresponding to the magnetic flux sensitivity of 6 x 10(-17) Wb. Noise reduction techniques are also discussed.
