Improving the spatial resolution of optical microscopes is important for a vast number of
applications in the life sciences. Optical microscopy allows intact samples and living cells to …

During the last decade, various efforts have been undertaken to enhance the resolution of
optical microscopes, mostly because of their importance in biological sciences. Herein, we …

The large consumer market has made cellphone lens modules available at low-cost and in
high-quality. In a conventional cellphone camera, the lens module is used to demagnify the …

Optical microscopy and manipulation methods rely on the ability to focus light to a small
volume. However, in inhomogeneous media such as biological tissue, light is scattered out …

Using spatially non-uniform illumination significantly improves the resolution of light
microscopy. Indeed, frequency mixing between the object and the illumination permits the …

We demonstrate a lensfree dual-mode holographic microscope that can image specimens in
both transmission and reflection geometries using in-line transmission and off-axis reflection …

We demonstrate 3D phase and absorption recovery from partially coherent intensity images
captured with a programmable LED array source. Images are captured through-focus with …

We report a novel light microscopy method for high resolution molecular imaging of thick
biological tissues with one photon excited fluorescence. Effective optical sectioning and …

A mouse skull is a barrier for high-resolution optical imaging because its thick and
inhomogeneous internal structures induce complex aberrations varying drastically from …

Light microscopy of thick biological samples, such as tissues, is often limited by aberrations
caused by refractive index variations within the sample itself. This problem is particularly …
