Comparison of two Methods for Wavefront Measurement of Terahertz Pulses Combined with 2D Electro-Optic Imaging
Résumé
We compare two methods of wavefront analysis of THz pulses associated with a 2D electro-optic imaging system. The first one is the standard Hartmann sensor, and the second one is based on the well-known fact that EO sampling can record the phase variation of the THz electric field.
