摘　　要：通过自行设计制造色分离器、一维发射系统、提升反射镜组件 ,将丹麦 DAN TEC的二维L DV改造为三维 L DV。提出了镀膜分光和紫光滤光片提纯相结合的最佳分色方案 ,并研制了镀膜分色片、紫光滤光片这两种关键部件。通过联调试验和校准试验 ,证明本三维 LA 2D\|LDV of Denmark DANTEC company is transformed into a 3D\|LDV by designing and manufacturing a colour separator,an one dimensional optical transmitting system and a mirror assembly for raising light by ourselves.The best splitting colours scheme is proposed in this paper,that is dividing colours by film\|plating and purifying violet colour by a filter.The key parts—a film\|plated colour separating filter and a violet colour filter—are developed.Through the unitive test and the calibrating test,it is verified that our 3D\|LDV system has reached the designed technique target completely.
