摘要

本研究是设计一种带有PDIC(鉴相集成电路)的蓝光和DVD设备拾取头。我们使用一个菱形棱镜与两个激光二极管平行。利用全息光学元件(HOEs)将来自不同光源的光束反射到同一PDIC上。减小了拾取头的几何尺寸和光学元件。Keywordspickup头;锄头;菱形棱镜;PDIC

Unitary Sensor of Blu-Ray and DVD Pickup Device

This study is to design a pickup head of Blu-ray and DVD device with one PDIC (phase detector integrated circuit). We use a rhomboid prism in parallel with two laser diodes. And HOEs (Holographic optical element) are used to reflect beam from different light sources and make them on the same PDIC. The geometrical size and optical components of the pickup head are reduced. Keywordspickup head;HOE; rhomboid prism; PDIC
