Optical Coherence Tomography (OCT) is a widely used imaging technique that has become an essential tool in ophthalmology. OCT measures the time delay and intensity of backscattered light from ...
Single-beam femtosecond laser pulses can surpass the diffraction limit of conventional focusing systems, enabling deep sub-waveguide single-spot modifications via nonlinear absorption at the focus.
Caltech’s new technique, called Compressed Ultrafast Planar Polarization Anisotropy Imaging (CUP2AI), enables real-time, non-invasive, wide-field fluorescence polarization measurements that can ...
