Towards a mobile quantitative phase imaging microscope with smartphone phase-detection sensors
Xiangjiang Bao, Zheng-da Hu, Lucas Kreiss +2
Quantitative phase imaging (QPI) enables visualization and quantitative extraction of the optical phase information of transparent samples. However, conventional QPI techniques typ…
Wide-Field Reflective Imaging with an Epi-Illumination Multi-Camera Array Microscope
Xiangjiang Bao, Lucas Kreiss, Clare B. Cook +3
We present an epi-illumination multi-camera array microscope (epi-MCAM) designed for wide-field reflective imaging of non-transparent samples. The epi-MCAM contains 24 tightly pack…
Curvature-adaptive gigapixel microscopy at submicron resolution and centimeter scale
Xi Yang, Haitao Chen, Lucas Kreiss +5
Large-area microscopy with submicron resolution is limited by tradeoffs between field of view (FOV), resolution, and imaging speed. Samples are rarely flat across centimeter-scale…
Large-scale compressive microscopy via diffractive multiplexing across a sensor array
Kevin C. Zhou, Chaoying Gu, Muneki Ikeda +6
Microscopes face a trade-off between spatial resolution, field-of-view, and frame rate -- improving one of these properties typically requires sacrificing the others, due to the li…
Detecting immune cells with label-free two-photon autofluorescence and deep learning
Lucas Kreiss, Amey Chaware, Maryam Roohian +7
Label-free imaging has gained broad interest because of its potential to omit elaborate staining procedures which is especially relevant for in vivo use. Label-free multiphoton mic…
Recording dynamic facial micro-expressions with a multi-focus camera array
Lucas Kreiss, Weiheng Tang, Ramana Balla +9
We present an approach of utilizing a multi-camera array system for capturing dynamic high-resolution videos of the human face, with improved imaging performance as compared to tra…
