Lcd Projector Optical Engine The Chroma Photometric Quality Analysis And Research

The paper does research on the qualities of the chroma and luminosity of the optical engine system of the LCD projector. In the paper, each of the optical components of the LCD optical engine is analyzed and their effect on the qualities of the chroma and luminosity is analyzed too. The conclusion that the color separating and combining system is the main effect on the qualities of the chroma and luminosity is presented. Based on the chroma theory, an estimating system of the qualities of the chroma and luminosity of the LCD optical engine and the mathematic model are established. According to the mathematic model, the software to analyze the qualities of the chroma and luminosity and optimize the LCD optical engine is developed with the C++ language. The results of the experiment are provided in the last section of this paper. They prove the proposed estimating system and mathematic model are right and the data of the software has high accuracy and high reliably.
