Invited Article: Mask-modulated lensless imaging with multi-angle illuminations

APL Photonics, 2018
The use of multiple diverse measurements can make lensless phase retrieval more robust. Conventional diversity functions include aperture diversity, wavelength diversity, translational diversity, and defocus diversity.

Quantitative phase imaging verification in large field-of-view lensless holographic microscopy via two-photon 3D printing

Scientific Reports
Large field-of-view (FOV) microscopic imaging (over 100 mm2) with high lateral resolution (1–2 μm) plays a pivotal role in biomedicine and biophotonics, especially within the label-free regime.

High Resolution Lensless Terahertz Imaging and Ranging

IEEE Access, 2019
In this paper, we propose a fast terahertz time-domain imaging method using a radar migration algorithm. We demonstrate high-resolution imaging in reflection without any collimating or focusing optics in the terahertz beam.

Mesoscopic calcium imaging in a head-unrestrained male non-human primate using a lensless microscope

Nature Communications
Mesoscopic calcium imaging enables studies of cell-type specific neural activity over large areas. A growing body of literature suggests that neural activity can be different when animals are free to move compared to when they are restrained ...
