Researchers have developed a spiral-shaped lens that maintains clear focus at different distances in varying light conditions. The new lens works much like progressive lenses used for vision correction but without the distortions ...
Photonic integrated circuits are an important next-wave technology. These sophisticated microchips hold the potential to substantially decrease costs and increase speed and efficiency for electronic devices across a wide ...
Integral imaging (II) display is one of the most promising near-eye displays (NEDs) due to its compact volume, full parallax, convenient full-color display, and, more importantly, true-3D and more realistic depth perception ...
For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and stable laser sources that ...
Metamaterials, famously likened to Harry Potter's invisible cloak, are artificial nano structures designed to manipulate light properties. However, the practical application of this technology in everyday life depends on ...
Researchers report new upgrades to a computational miniature mesoscope that enable single-shot, 3D high-resolution imaging with a wide field of view. The simple, low-cost miniature instrument could be useful for a wide range ...
In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped surfaces requires measuring ...
As a structure composed of two-dimensional arrays of microscale lenses, micro-lens array (MLA) has attracted the attention of both academia and industry due to its distinctive optical properties and wide applications. Recently, ...
Diamond nanocrystals, namely nanodiamonds, which host point defects such as nitrogen-vacancy (NV) centers, are a promising quantum material.
Researchers have developed a way to create freeform optical components by shaping a volume of curable liquid polymer. The new method is poised to enable faster prototyping of customized optical components for a variety of ...
