Miniaturized Projection Systems in Custom Jewelry: Optical Engineering Breakthroughs

Abstract:
This paper explores the integration of micro-projection technology into bespoke jewelry, focusing on optical design challenges. We analyze laser diode efficiency, diffractive optical elements (DOEs), and thermal management systems required to fit projection modules within 5mm3 volumes. Case studies demonstrate 80% brightness retention after 100 hours of continuous operation, achieved through nanocrystalline diamond heat sinks.
