Quantitative Decomposition of Speckle Decorrelation for Inverse Problems in Complex Wave Scattering
Qihang Zhang, Haoyu Yue, Ninghe Liu +4
Optical scattering remains one of the richest phenomena to study in classical optics. Wavefronts that are severely distorted due to scattering still carry significant information a…
Optimized cerebral blood flow measurement in speckle contrast optical spectroscopy via refinement of noise calibration
Ninghe Liu, Yu Xi Huang, Simon Mahler +1
Speckle contrast optical spectroscopy (SCOS) offers a non-invasive and cost-effective method for monitoring cerebral blood flow (CBF). However, extracting accurate CBF from SCOS ne…
Ptychographic non-line-of-sight imaging for depth-resolved visualization of hidden objects
Pengming Song, Qianhao Zhao, Ruihai Wang +6
Non-line-of-sight (NLOS) imaging enables the visualization of objects hidden from direct view, with applications in surveillance, remote sensing, and light detection and ranging. H…
Sparsity-regularized coded ptychography for robust and efficient lensless microscopy on a chip
Ninghe Liu, Qianhao Zhao, Guoan Zheng
Coded ptychography has emerged as a powerful technique for high-throughput, high-resolution lensless imaging. However, the trade-off between acquisition speed and image quality rem…
