AB - Ultrafast shadowgraphy is a new experimental technique that uses few cycle laser pulses to imagedensity gradients in a rapidly evolving plasma. It enables structures that move at speeds close tothe speed of light, such as laser driven wakes, to be visualized. Here we study the process of shadowgraphicimage formation during the propagation of a few cycle probe pulse transversely througha laser-driven wake using three-dimensional particle-in-cell simulations. In order to construct syntheticshadowgrams a near-field snapshot of the ultrashort probe pulse is analyzed by means ofFourier optics, taking into account the effect of a typical imaging setup. By comparing syntheticand experimental shadowgrams we show that the generation of synthetic data is crucial for the correctinterpretation of experiments. Moreover, we study the dependence of synthetic shadowgramson various parameters such as the imaging system aperture, the position of the object plane andthe probe pulse delay, duration and wavelength. Finally, we show that time-dependent informationfrom the interaction can be recovered from a single shot by using a broadband, chirped probe pulseand subsequent spectral filtering.
