Holo-Imprinting Used for Mass Production of Planar Liquid Crystal Optics

Planar liquid crystal (LC) optics has recently gained popularity as a new holographic optical element (HOE). Planar LC optics demonstrates unique properties such as polarization selectivity, dynamic modulation, and broad angular and spectral bandwidths, in addition to the capacity to record and recreate arbitrary wavefronts as in classic HOEs.

Tiny Switches Dramatically Increase the Resolution of Chip-Based LIDAR

When Google unveiled its first autonomous cars in 2010, the spinning cylinder mounted on the roofs really stood out. It was the vehicle's light detection and ranging (LiDAR) system, which worked like light-based radar. Together with cameras and radar, LiDAR mapped the environment to help these cars avoid obstacles and drive safely.

Two-Wavelength Holographic System Measures the Topography of Melt Pool During Laser Beam Melting

Additive manufacturing is a key technology for industry that allows building structures by progressive addition of material, with complex geometries. One of the main techniques is the laser beam melting process which consists of successively melting metal or ceramic powder layers to manufacture 3D mechanical structures.
