Novel optical devices for gene disease diagnostics system

摘要

Binary optics has been interested widely in recent years, where the optical elements can be fabricated on a thin glass plate with micro-ion-etching film layer. A novel optical scanning system for gene disease diagnostics is developed in this paper, where four kinds optical devices are used, such as beam arrays splitter, arrays lens, filter arrays element and detection arrays. A soft for binary device designing with iterative method is programmed. Two beam arrays splitters are designed and fabricated, where one devices can divide a beam into the 9 * 9 arrays, the other will divide a beam into the 13 * 13 arrays. The beam arrays splitter has a good diffraction efficiency >70%, and an even energy distribution. The gene disease diagnostics system is portable by biochip and binary optics technology.
