Ara\u015ft\u0131rma ekibi geli\u015ftirdikleri sistemi “Digital Incoherent Synthesis of Holographic Light Fields” (DISH) olarak adland\u0131r\u0131yor. Y\u00f6ntem, fotopolimer re\u00e7ineyi katman katman sertle\u015ftirmek<\/strong> yerine, sabit bir re\u00e7ine hacmi i\u00e7inde \u00fc\u00e7 boyutlu bir \u0131\u015f\u0131k yo\u011funlu\u011fu<\/strong> da\u011f\u0131l\u0131m\u0131 olu\u015fturarak nesnenin tamam\u0131n\u0131 ayn\u0131 anda k\u00fcrl\u00fcyor.<\/p>\n

Mevcut hacimsel bask\u0131 teknikleri, \u00f6rne\u011fin computed axial lithography (CAL)\u00a0 genellikle \u0131\u015f\u0131k kayna\u011f\u0131n\u0131 veya re\u00e7ine haznesini d\u00f6nd\u00fcrerek farkl\u0131 a\u00e7\u0131lardan projeksiyon yap\u0131yor. Bu mekanik hareket hem karma\u015f\u0131kl\u0131k yarat\u0131yor hem de h\u0131z ve stabiliteyi s\u0131n\u0131rlayabiliyor.
