Breathalyzers – Optical Sensor Integrated Into Smartphone Screen

Researchers have developed the first silicon chip compact 3D LiDAR imaging system that can match and exceed the performance and accuracy of most advanced, mechanical systems currently used. 3D LiDAR can provide accurate imaging and mapping for many applications; it is the “eyes” for autonomous cars and is used in facial recognition software and by [..]

Metaform Optics - VR Head-Mounted Display

Scientists have created interactive, slim-paneled holographic screens (displays) that increase the viewing angle for 3D videos by 30 times. The ultra-thin glass prototype could make it easier to incorporate holographic video displays into mobile devices in the future.  The team has used their holographic screens to view a full-screen, 4K interactive video of a swimming [..]

Metaform Optics - VR Head-Mounted Display

For some applications, such as microprojection and augmented and virtual reality (AR/VR), researchers continue to chase ever-smaller pixel sizes (nanopixels) and higher pixel densities. And these efforts eventually run up against some practical limitations, particularly on pixel brightness, that are imposed by the 2D-patterning approaches commonly used to create display pixels. Now, researchers have proposed [..]

Nanocomposite Improves Liquid Crystal Lens Response

The emerging, interdisciplinary science of metasurfaces has fascinated optical and photonic scientists and engineers, who see these high-tech materials as a route toward a new generation of ultra-compact flat optics such as photographic lenses. But most metasurfaces demonstrated thus far have been predesigned for a single functionality; only recently have researchers begun to explore the [..]

Metaform Optics - VR Head-Mounted Display

A new chip-based device that can shape and steer blue light could significantly reduce the size of the light projection components used in emerging applications such as VR display, autonomous vehicles, optogenetics, and even trapped-ion quantum computers. Researchers have made an optical phased array (OPA) with a wide field of view that contains no moving [..]
