a Experimental setup for the polarization-gating field generation, including a birefringent quartz crystal (optical axis is 45° to the \(x\)-direction) and a quarter-wave plate (optical axis is along \(y\)-direction). b The 3D spatiotemporal polarization direction (white arrows) and intensity (color map) profiles of the polarized-gating fields. c The temporal intensity (blue line) and ellipticity \({\xi }^{({x}_{0},{y}_{0})}(t)\) (red line) of the polarization-gating field at the point \(({x}_{0},{y}_{0})\). d The time-dependent polarization parameters \({\psi }^{\left({x}_{0},{y}_{0}\right)}\left(\omega \right)\) and \({\varDelta }^{\left({x}_{0},{y}_{0}\right)}\left(\omega \right)\) at the point \(({x}_{0},{y}_{0})\).
