Controlling light at dimensions thousands of times smaller than the thickness of a human hair is one of the pillars of modern ...
Please join the Lowell Center for Space Science and Technology on Thursday, Sept. 18 at 11 a.m. the the talk "Deployable Diffractive Optical Elements for Small Satellite Lidar Missions" by Adam ...
ABSTRACT: This study presents a comprehensive analysis of the most important criteria influencing the precision glass molding (PGM) cycle, which was proposed using the finite element (FE) method ...
Abstract: As a commonly used instrument, imaging spectrometers can measure the 3-D data cube of targets. In order to detect the spectral information of dynamic targets, different kinds of snapshot ...
Many of the world’s largest telescopes — whether on the ground, in the air, or in space — use mirrors as their primary optical element. Mirrors have the advantage of being flat and lightweight, ...
A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240181, discusses high-efficiency achromatic liquid crystal diffractive optical elements. Augmented reality (AR) and virtual ...
Now you see it: A schematic of the experiment, in which an optical diffractive camera hides information by concealing it within ordinary-looking “dummy” patterns. (Courtesy: A Ozcan) Information ...
