摘要： A testing method is configured for testing parameters of a color wheel. The color wheel includes a color filter, which includes three sector-shaped filter segments and a motor for driving the filter segments of the color filter to rotate. The color filter is driven to rotate. Light is emitted toward the color filter of the color wheel, and reflected back by the color filter. Boundary impulses are generated according to changes in intensity of the light reflected back by the color filter. Based on relationships between the boundary impulses, central angles of the filter segments of the color wheel are calculated.

摘要： The present invention proposes a reflective type liquid crystal projection system, which comprises an incident light source providing an S-polarization light beam or a P-polarization light beam as the incident light beam. A polarization of color-splitting device having a first polarization of color splitter and a second polarization of color splitter is used to split the incident light beam of three primary colors into two sets of light beams, which respectively penetrate through or are reflected. The two sets of light beams split by the first polarization of color splitter are reflected by two reflective mirrors, traverse two polarizing plates arranged between the reflective mirrors and the second polarization of color splitter, and are then incident on the second polarization of color splitter. At least a retarder is arranged between the reflective mirrors and the polarization of color-splitting device. The split light beams of three primary colors are assembled into an output light beam by a color-combining device comprising three PBS's. Finally, the output light beam is projected to form the image via a projection lens.
