In the past two decades or so, there has been a renaissance of optical microscopy research
and development. Much work has been done in an effort to improve the resolution and …

Wide field-of-view (FOV) and high-resolution imaging requires microscopy modalities to
have large space-bandwidth products. Lensfree on-chip microscopy decouples resolution …

Compressive sampling enables signal reconstruction using less than one measurement per
reconstructed signal value. Compressive measurement is particularly useful in generating …

We demonstrate a microwave imaging system that combines advances in metamaterial
aperture design with emerging computational imaging techniques. The flexibility inherent to …

In recent years compressive sensing (CS) has been successfully introduced in digital
holography (DH). Depending on the ability to sparsely represent an object, the CS paradigm …

To achieve high-resolution and wide field-of-view, digital holographic imaging techniques
need to tackle two major challenges: phase recovery and spatial undersampling. Previously …

Based on partially-coherent digital in-line holography, we report a field-portable microscope
that can render lensfree colour images over a wide field-of-view of eg,> 20 mm2. This …

Limited-angle tomography of an interior volume is a challenging, highly ill-posed problem
with practical implications in medical and biological imaging, manufacturing, automation …

Lens-free holographic on-chip imaging is an emerging approach that offers both wide field-
of-view (FOV) and high spatial resolution in a cost-effective and compact design using …

Low-light imaging is challenging in regimes where low-noise detectors are not yet available.
One such regime is the shortwave infrared where even the best multipixel detector arrays …
