Active manipulation of light beams is required for a range of emerging optical technologies, including sensing, optical computing, virtual/augmented reality, dynamic holography, and computational imaging.
Stanford researchers in the Vuckovic group have developed an optical phased array (OPA) for solid-state beam-steering in optical systems such as LIDAR, projectors, and microscopy.
This invention facilitates the realization of optical elements with spatially multiplexed/interleaved phase profiles to achieve a high packing density of distinct optical elements on a surface.
Researchers at Stanford have developed a dielectric diffraction grating that provides high (near-unity) diffraction efficiencies in an ultra-compact volume.
Stanford researchers at the Dionne Lab have introduced new vibrational spectroscopy, termed electron- and light induced stimulated Raman (ELISR) scattering, in electron microscopy for simultaneous high-resolution chemical mapping of various samples.
Stanford researchers at the Prakash Lab have developed Octopi, a low-cost ($250-$500) and reconfigurable autonomous microscopy platform capable of automated slide scanning and correlated bright-field and fluorescence imaging.
Stanford researchers at the Kasevich Lab have developed a module that can attach to any standard optical system or sensor for wide-field, time-resolved imaging.
Stanford researchers at the Kasevich Lab have prototyped a multi-pass electron microscope that can image nanometer scale samples including electron damage sensitive proteins and other electron dose sensitive nanostructures with low damage.
Researchers in Prof. Mark Schnitzer's laboratory have developed a two-photon scanning microscope for imaging neural activity in a 2x2mm field of view while maintaining a fast scanning rate (~10Hz image update frequency).
Stanford researchers successfully manufactured high quality optical components using commercially available 3D printing. The 3D printed optics were easy to fabricate and inexpensive.
Stanford researchers have developed a lanthanide-doped upconverting nanoparticle (UCNP) that emits very photostable and non-blinking light, and is bright enough to delineate tumor boundaries to the naked eye during surgery.
Researchers in Prof. W.E. Moerner's laboratory have developed a compact point spread function (PSF) that enables optical imaging in three dimensions with nanoscale precision using a limited number of photons.
Stanford researchers have designed a tunable wedge-based phase mask for 3D super-resolution imaging that can simultaneously determine both the position and rotational mobility of individual light-emitting molecules from a single camera image.
Researchers in Prof. Karl Deisseroth's laboratory have developed a highly precise, scalable optical system for imaging or controlling thousands of individual neurons in the 3D volume accessible with a single multiphoton fluorescent microscope objective.
An interdisciplinary team of Stanford researchers is developing a dual axis confocal (“DAC”) microscope system for in vivo imaging of tissues at the cellular scale.
