摘要(英) |
Along with the development of technology, the application of the pico projector becomes diversified in recent years. It’’s widely used in the portable devices like Mobilphone, Digital Camera and Digital Vedio and has become the one of thenew technical products.
This thesis is focused on the optical design of DLP pico-projector system. Thecontent of this design includes the Illumination System and Image OpticalSystem. Then evaluating the optical performance and efficiency of this pico-projector.
In light source module, we choose the high power LED lamp and use collimator lens and dichroic filter for RGB light combiner. In regard to the light engine design, we use a Mirror type structure to replace the traditional TIR structure for a higher efficiency and a lower cost. Besides, we use a lens array and design the Projection Lens with 4pcs lenses to reduce the optical volume to 6.8 c.c.. The simulation result can reach the target that the brightness is higher than 10 lm/W and JBMA uniformity is better than 90%.
