Abstract:
We present a quantitative shadowgraphic method that can measure the density of a laser-generated plasma in air. Simultaneous comparison of both shadowgraphy and interferometry has been carried out, allowing the experimental evaluation of the reliability of the shadowgraphic method. Even though limited by absorption in the sample, shadowgraphy performs better in terms of sensitivity.
