## Abstract

The broader impact/commercial potential of this Small Business Technology Transfer (STTR) Fast-Track project is to make advanced 3D display technology easier and safer for students to use. The team is creating the first student-friendly optical trap display (OTD) system using tiny lights called micro-LEDs. Unlike older versions that needed lasers and safety gear, this version is safe for classrooms. Through a program called “Hunt for the Hologram,” students will do real research by finding particles that can be trapped with light and using them to create floating images in the air. This helps students build skills like spatial reasoning and problem-solving. The new technology also costs less and is easier to use, with potential for wide use in STEM education and future uses in fields like medical imaging and micro-manufacturing.

The proposed project will investigate whether micro-LED arrays can provide bright, independent illumination to multiple optically trapped particles in partial vacuum, overcoming technical limitations of laser-based systems. Phase I will optimize particle trapping (target: 20+ stable traps), evaluate brightness (target: 200+ nits per particle), and validate user experience through design-based research. Key innovations include using spatial light modulators and holographic optical elements to direct micro-LED light to specific 3D positions, allowing multiple viewers to observe floating images. Phase II will develop a portable, compliant, and manufac
