Digital Three-Dimensional Modeling of Heritage by Frequency-Modulated Laser Radar: the case of Donatello’s "David"
نویسنده
چکیده
In this paper the application of a novel CW FM Laser radar is demonstrated through the acquisition of a three dimensional model of the world famous "David" by Donatello. The steps of the acquisition procedure and the related technical solutions are reported. The scientific focus was centered on the processing pipeline simplification due to this new acquisition methodology. Detailed results are presented, demonstrating how the use of this new generation of sensors allows the digitalization of artwork, made of materials that are normally very difficult to acquire, and to improve the overall level of modeling accuracy.

We solved one dimensional Schrodinger equation in a H2+ molecular environment by using 3 femtosecond homogeneous and nonhomogeneous laser fields. In homogeneous case, we found out that larger inter nuclear distances result in earlier ionization and also more instability in the wave packet. We deducted that the more the instability is, the more modulated the power spectrum will be. So, by choosi...
