    "abstract": "We present a quantitative shadowgraphic method which can measure the density\nof a laser-generated plasma in air with sensitivity and resolution comparable\nor better than traditional interferometric techniques. Simultaneous comparison\nof both shadowgraphy and interferometry has been carried out allowing the\nexperimental evaluation of the reliability of the shadowgraphic method.",
