| Popis: | 96 In general, a thesis topic of Projection System, it is very seldom to see an implementation study for Image Optical System and Non-Image Optical System simultaneously. I am using the Optical Software to generating a simulation test in terms of the performance result for study and analysis. First of all, the Non-Telecentric and offset front projection system was the main focus study in my dissertation. It includes the pragmatic optical design of Illumination system and Image Optical System.. To follow the trend of Cost Down, I have simplified the design with less lenses after the system specified. The Study was planned with two directions as below. 1. Projection Lens (Image Optical System): An application of two sets of six lenses (all spherical lenses) was using on the Non-Telecentric Front Projection. The evaluation was focus on the performance review and the tolerance limitation analysis. 2. Illuminative System (Non-Image Optical System): Follow with Kohler theory, with etendue and geometric optical formula we got a best size of ROD. A set of three pieces lens (2 spherical lenses and 1 aspheric lens) generated a best illuminative path through ZEMQX software. Then adding the Lamp, UVIR filter, Color Wheel and Rod as a complete illumination system. The performance result was evaluated with ASAP simulation software. Offsetting the light valve and illumination system were selected. The Projection Efficiency and Image Uniformity were evaluated on an Integration Projection System for the two tasks above. A summary with conclusion as follows. |
