Using multiplexed broadband ptychography, we characterize the EUV light from high-order harmonic generation. The method allows for spectrally resolved complex beam profiles to be imaged for different harmonic outputs without grating dispersion.

We present diffractive networks that can all-optically classify spatially-overlapping phase objects. Individual phase images of the overlapping objects are also reconstructed using electronic networks that process the compressed signals, all-optically synthesized by a diffractive network.

A light field local surface features detection method is proposed based on the scale space established on the moving frame determined by the depth information. Experimental results show more detected features than SIFT and LiFF.

The modal holographic wavefront sensor enables fast measurements of individual aberration modes without the need for time-consuming calculations. To minimize the effect of inter-modal crosstalk on the measurement accuracy, we present sensor optimization and show its performance in closed-loop adaptive optics in simulation.
