The polarized monochromatic light beam is reflected by the first reflecting mirror, transformed to a light beam with reversed polarization by the half-wave plate, and output to the first polarization separator. The polarized bichromatic light beam is reflected by the second reflecting mirror to the second polarization separator for polarization splitting, and then transmitted to the color separator for separating the two primary colors. The image modulation devices are arranged on sides of the first modulating the incident monochromatic and bichromatic light beams. The projection lens is disposed on one side of the second polarization separator.

摘要： An automatic focusing projecting device includes an image light source, a first image lens, an image sensor, a second image lens, a memory, a microprocessor, and at least a driving device. The image light source projects an image onto a screen through the first image lens. The image sensor senses the image on the screen through the second image lens. The microprocessor calculates sensed signals from the image sensor to get a definition of the image, and then saves the definition in the memory. The microprocessor compares the definitions when the first image lens and the second image lens are moved to different positions to move the first image lens and the second image lens and locate the first image lens and the second image lens at their focusing positions respectively where the definitions of the image are the greatest.

The beam splitter has a first reflection side, on which a first splitter film is provided, and a second reflection side, on which a second splitter film is provided. An angle between a normal line of the first reflection side, and a normal line of the second reflection side, is in a range between 165 degrees and 180 degrees.
