Abstract: Abstract In acousto-optic imaging, the ultrasound-induced optical phase modulation has been widely used in the imaging of biological tissue. However, in Raman-Nath diffraction, the phase of diffracted light has not attracted much attention. Additionally, each… read more here.

Abstract: Intensity diffraction tomography (IDT) provides quantitative, volumetric refractive index reconstructions of unlabeled biological samples from intensity-only measurements. IDT is scanless and easily implemented in standard optical microscopes using an LED array but suffers from large… read more here.

Abstract: We propose a novel intensity diffraction tomography (IDT) reconstruction algorithm based on the split-step non-paraxial (SSNP) model for recovering the 3D refractive index (RI) distribution of multiple-scattering biological samples. High-quality IDT reconstruction requires high-angle illumination… read more here.

Abstract: Recovering 3D phase features of complex biological samples traditionally sacrifices computational efficiency and processing time for physical model accuracy and reconstruction quality. Here, we overcome this challenge using an approximant-guided deep learning framework in a… read more here.
