An exciting prospect in modern optics is to exploit patterns of light — how the light looks in its many degrees of freedom — often referred to as “structured light.” Each distinct pattern could form ...

Scientists used a new invariant property of vectorial light to encode information. This quantity, which the team call 'vectorness', scales from 0 to 1 and remains unchanged when passing through a ...

Structured light can significantly enhance information capacity, due to its coupling of spatial dimensions and multiple degrees of freedom. In recent years, the combination of structured light ...

Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's ...

Active depth sensors, such as lidar, time-of-flight (TOF) systems, and structured light (SL) systems, can evenly sample the depth of an entire scene at a predetermined scan rate. SL-based ...

Photonics researchers from Tampere University, Finland, and Kastler-Brossel Laboratory, France, have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied ...

Schematic illustration of the DFAMFPP principle: Multiple dual-frequency fringe patterns are overlaid in a single long-exposure image. A deep neural network then reconstructs time-resolved 3D shapes ...
