Fig. 1: The proposed WRSI for beam characterization.

From: Complete characterization of ultrashort optical pulses with a phase-shifting wedged reversal shearing interferometer

Fig. 1

a Schematic diagram of the experimental set-up. The y-wedge angle is highly exaggerated. b Top view of the beam splitter cube that operates as a WRSI. The dashed line shows the cross-section of the BSC at a different height from the base of the BSC. c Ray diagram of the WRSI when it is operating with maximum shear with the maximum beam size
