This means that by emitting pseudo-random pulses of light, a complete video <strong>can be acquired within a single image.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><img decoding=\"async\" src=\"https:\/\/qommtrue.cl\/optolab\/wp-content\/uploads\/2023\/11\/Nota-Optolab_Arreglo-de-ca\u0301maras-edited.jpg\" alt=\"\" class=\"wp-image-1585\" width=\"318\" srcset=\"https:\/\/qommtrue.cl\/optolab\/wp-content\/uploads\/2023\/11\/Nota-Optolab_Arreglo-de-ca\u0301maras-edited.jpg 633w, https:\/\/qommtrue.cl\/optolab\/wp-content\/uploads\/2023\/11\/Nota-Optolab_Arreglo-de-ca\u0301maras-edited-225x300.jpg 225w\" sizes=\"(max-width: 633px) 100vw, 633px\" \/><\/figure><\/div>\n\n\n<p>Felipe Guzm\u00e1n explains, \u00abIt is the first time that a high-power pulsed illuminator of this nature has been created.
