High-density holography

Example of a high-quality hologram generated by a spatial light modulator approach that eliminates crosstalk between different depth planes by using pre-shaped wavefronts with random phase. The result is large-volume, high-density, 3D projections containing up to 1,000 simultaneous image planes.

    By tailoring the anisotropy of light scattering along the surface of a macroscopic flat object, mechanical stabilization can be achieved without focused incident light or excessive constraints on the shape, size or material composition of the object.

    The cost of infrared detectors has limited the deployment of multispectral imagers and sensors. Researchers now demonstrate simple quantum-dot devices that promise fast, sensitive and low-cost cameras that can switch between short- and mid-wavelength infrared.
