Claims

C1strongest claim

we propose an ultrafast, wide-field pump-probe interferometric microscope on a telecentric platform that significantly extends the effective DoF to ~18 micrometer at a high NA of 0.9 while maintaining high spatial resolution (down to 235 nm) and temporal resolution (~170 fs). The system enables single-frame 3D topography reconstruction without axial scanning or multi-view acquisition.

C2weakest assumption

The interferometric reconstruction on the telecentric platform accurately recovers 3D topography from a single frame across the extended DoF without introducing artifacts or losing resolution in dynamic pump-probe measurements.

C3one line summary

Ultrafast wide-field interferometric microscope extends effective depth of field to 18 μm at NA 0.9 for single-shot 3D topography with 235 nm spatial and 170 fs temporal resolution.
