Three-dimensional (3D) imaging is essential for investigating cellular structure and dynamics. Traditional optical methods ...

Light with helical phase wavefront carries orbital angular momentum, a unique feature widening the horizon of optical imaging applicability. Here, we take particular interest in the common but ...

The results of optogenetic stimulation are usually evaluated by immunofluorescence or flow cytometry, and the observation of transient responses after stimulation, as in cardiac electrophysiology ...

Scientists have discovered a centrosymmetric crystal that behaves as though it is chiral – absorbing left- and right-handed ...

Optical microscopes that measure light scattered from, or emitted by, buried transistors are also essential in circuit analysis.

“Transmission polarized optical microscopy of short-pitch cholesteric liquid crystal shells,” in Proc. SPIE 9769, Emerging Liquid Crystal Technologies XI, 97690U.

The resulting films were characterized with polarized optical microscopy; photographs and analysis of the films as a function of the comprising nanotube length fractions are reported in Figure 3.

We present a new nonlinear optical technique to probe chirality, i.e., lack of reflection symmetry, of surfaces and thin molecular films. The technique is based on second-harmonic generation and ...
