Model-based deep learning enables time-resolved computational microscopy

PhotoniX
Computational microscopy combines advances in optical hardware and signal processing to push the boundaries of imaging resolution and functionality. However, acquiring extended information often comes at the expense of temporal resolution.

High dynamic range lensless on-chip microscopy via an overexposure inverse-projection operator

Lensless on-chip microscopy (LoM) enables high-throughput, label-free imaging with a compact setup and high numerical aperture. Its performance is limited by sensor saturation, which distorts high-intensity measurements and degrades reconstruction of the

Lensless digital holographic microscopy and its applications in biomedicine and environmental monitoring

, 2018
Optical compound microscope has been a major tool in biomedical imaging for centuries. Its performance relies on relatively complicated, bulky and expensive lenses and alignment mechanics.

Ultrastable XUV interferometry for broadband lensless imaging

, 2014
Lensless imaging is the technique of numerically reconstructing an image of a sample instead of imaging the sample on the camera using lenses. This is an interesting solution for microscopy with extreme ultraviolet (XUV) and X-ray radiation, as good ...

Near-field nano holographic tomography with chemical contrast exploiting low-dimensionality constraints

JPhys Photonics
X-ray absorption near-edge structure (XANES) spectroscopy is key to understanding functional materials. We present, to our knowledge, the first use of hard x-ray near-field holography (NFH) for three-dimensional (3D), spatially resolved XANES.

Field-portable quantitative lensless microscopy based on translated speckle illumination and sub-sampled ptychographic phase retrieval

, 2019
We report a compact, cost-effective and field-portable lensless imaging platform for quantitative microscopy. In this platform, the object is placed on top of an image sensor chip without using any lens. We use a low-cost galvo scanner to rapidly scan an
