Sub-Cellular Imaging and Manipulation via Hyper-Numerical Aperture Imaging Surfaces

High spatial resolution and detection of sub-cellular physiology (like respiration) is achieved using a near-field imaging surface that can be manipulated mechanically inside living biological matter. This new near-field probe is photon efficient, unlike most near-field scanning probes, and is a true imaging probe, not a point source or point collector....

Hybrid MOD-Enmat Lens

Researchers at the University of Arizona have designed an optical device comprising a multiple-order diffractive Fresnel lens (MOD-DFL) and an achromatizing compensation mechanism that reduces refractive dispersion created by the MOD-DFL, thereby reducing the focal range of the MOD-DFL. A method is also provided of using the optical device in an image...

Multiple-Wavelength Quantitative Phase Imaging Technique

This invention is a new way to apply adaptive optics principles to image properties of biological cells. This method uses multi-spectral digital holographic imaging and random phase masks to extract phase maps comparable to maps from traditional quantitative phase imaging (QPI) optical systems though with less complication and expense. This method provides...
