Matt Willemsen<p>Harvard Scientists Control “Points of Darkness” for Remote Sensing and Covert Detection Applications<br>Harvard researchers have developed techniques to control “points of darkness” in light using metasurfaces. The team created precise dark spots that can capture atoms or act as measurement points for imaging, and developed resilient “polarization singularities,” stable dark spots in polarized optical fields.<br><a href="https://scitechdaily.com/harvard-scientists-control-points-of-darkness-for-remote-sensing-and-covert-detection-applications/?expand_article=1" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">https://</span><span class="ellipsis">scitechdaily.com/harvard-scien</span><span class="invisible">tists-control-points-of-darkness-for-remote-sensing-and-covert-detection-applications/?expand_article=1</span></a> <a href="https://fedibird.com/tags/RemoteSensing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>RemoteSensing</span></a> <a href="https://fedibird.com/tags/ControlPoints" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ControlPoints</span></a> <a href="https://fedibird.com/tags/CovertDetection" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>CovertDetection</span></a></p>
