American scientists have developed a technique to concentrate light energy and transmit it in the thinnest way possible, which is why it can be called a <strong>light needle<\/strong> or <strong>light pulse<\/strong>, as they themselves have named the discovery. Want to know more? Keep reading!<\/p>\n<h2>The Light Needle and its uses<\/h2>\n<p>Developed at the University of Rochester, USA, by scientists Miguel Alonso and Kevin Parker, the light needle is a new light beam pattern that, unlike most other beams, <strong>does not depend on the light wave source<\/strong>. It is manipulated in flight time, which gives this light beam an incomparable intensity, in addition to ensuring greater flexibility for the application of the technique.<\/p>\n<h3>Uses of the light pulse<\/h3>\n<ul>\n<li>Sharpness for ultrasound and radar images<\/li>\n<li>Possibility of creating new properties on material surfaces<\/li>\n<li>Precise holes in materials manufactured on a nanometric scale<\/li>\n<\/ul>\n<h3>How the light pulse was created<\/h3>\n<p>Miguel and Kevin observed that <strong>it is possible for a light wave to have an internal collapse in a nanosecond<\/strong> or even less time. The wave then forms an incredibly thin and intense light beam before the light expands. In other words, the energy concentrated in time gives rise to a light pulse.<\/p>\n<h3>Light Pulse in Optics<\/h3>\n<p>The smaller the light beam, the better the image resolution quality, as it is possible to separate very small things with precision. This pattern can be applied to <a href=\"https:\/\/azeheb.com\/categoria-produto\/all-products-en\/filtro\/optics-en-1-physics-en-1\">optics<\/a> in general, but also to microscopy, radar, and sonar, in addition to the already mentioned ultrasound.<\/p>\n<h3>In the industrial field<\/h3>\n<p>In the industrial field, the light pulse provides benefits for any form of laser processing. Cuts and welds, for example, will have the highest possible light intensity at a determined and precise point.<\/p>\n<p>That&#8217;s all for today!
