Single-Axis Ptychographic Coherent Diffractive Imaging for Spectroscopic and Wavefront Retrieval
Qijun You, Lingshuo Meng, Fangrui Quan +1
We present a novel axial ptychographic coherent diffractive imaging (AP-CDI) technique designed to overcome the critical throughput bottleneck of conventional methods. By replacing…
Interface and spectrum multiplexing ptychographic reflection microscopy
Yun Gao, Qijun You, Peixiang Lu +1
Reflective ptychography is a promising lensless imaging technique with a wide field of view, offering significant potential for applications in semiconductor manufacturing and dete…
Spatio-spectral light modulator of XUV high harmonics
Qi Zeng, Yimin Deng, Xinyue Yang +2
High-order harmonic generation (HHG), characterized by its highly nonlinear nature, often exhibits a complex spatio-temporal profile that poses challenges for practical application…
Spectral multiplexing based on multi-distance lensless imaging
Qijun You, Lingshuo Meng, Yun Gao +3
We have demonstrated the capability of spectral multiplexing in multi-distance diffractive imaging, enabling the reconstruction of samples with diverse spectral responses. While pr…
