ORLANDO, Fla., Feb. 20, 2020 — University of Central Florida (UCF) researchers have taken a step toward developing neuromorphic computers — computers that mimic neurobiological architectures present in the human nervous system — by demonstrating how to create a nanoscale device that can mimic the neural pathways of brain cells used for human vision. “Our group created a single device that mimics the eye and the brain function together,” professor Tania Roy said. “Our device can observe the image and recognize it on the spot.” The researchers grew perovskite quantum dots (PQDs)...Read full articleRelated content from Photonics MediaARTICLESSmart Glass Could Offer a New Route to Machine VisionA new type of smart glass, developed by a team at the University of Wisconsin-Madison, leverages optical reflection to recognize images without requiring sensors, circuits, internet connection, or...Vision Spectra Autumn 2019 IssueNanostructured Glass Is Based on Butterfly WingGlass for displays, tablets, laptops, smartphones, and solar cells needs to allow light to pass through, but could benefit from a surface that repels water, oil, and other liquids.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors) and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...Photonics HandbookSWIR Imaging: An Industrial Processing Tool: Short-wave infrared (SWIR) imaging with InGaAs-based cameras is well suited to nondestructive identification of materials, their composition, coatings and other characteristics.Imaging has long been used in industrial processes to measure, monitor, control or otherwise manage the production of goods.
