New description: [New technology field] This new type is a kind of fiber-optic hybrid technology, especially the green-difficult body projection system. [Prior Art] ‘shirt technology has been fully developed’ and is widely used in computer display, projection television, and field. _ 3D Lai animation, the need to read the age of the image, the vertical display technology has gradually become an important research direction of projection display. I have already seen the imaging system of the stereoscopic image of iij, which basically includes the projection subsystem. One of the projection subsystems projects the image of the left eye, and the other projection subsystem projects the image of the right eye. Stereo images can be seen with polarized glasses. Reading the squall line that reaches the 3D projection wire is not only high, but also the space required for the user to construct the projection system. If it is to be moved, it is more inconvenient for the user. [New content] The novel stereoscopic image projection system in the prior art has the disadvantages of high cost, large space requirement and inconvenient movement, and provides a simple read image projection system. The present invention provides a stereoscopic image projection system, comprising a projection lens having a receiving beam, the stereoscopic tearing-beautiful butterfly, and a polarization splitting module, converting the unpolarized light into polarized light, including: - - the polarization splitting surface is for the first polarity to produce a wide-angle light reflection, and the 帛-image unit receives the first-polar light and modulates it into (four) dipolar light, the shape, the second-picture element, and receives the - yaguang And modulated into the first _ polar light with the image signal, and then reflected. M37.4590 The high-intensity social-sequence line of this new type is implemented. Compared with the financial technology, this new type adopts a simple structure to realize the projection display of stereoscopic images, and the feeding system requires small space and convenient transportation. In the ribbed polarized wire separation and polarization splitting module, the first-light and the second-polar light are subjected to multiple transitions, and the first-polar light and the second-polar light reaching the projection lens have better isolation and more High purity, improved contrast, and viewers can see stereoscopic images. [Embodiment] The above-mentioned and other technical contents 'features and effects of the present invention' will be clearly described in the following five touch implementations in conjunction with the w diagram. Figure 2 is a schematic circle of a projection system in accordance with a first embodiment of the present invention. As shown in FIG. 1, the W system 1 GO includes a light source module 1 for emitting unpolarized light, a light source (10) and a random inspection (10) for converting unpolarized light into polarized light and making a fresh signal.

Light source pull,! 101 includes a lens group (10) that rotates one or more optical elements of the non-polarized filament, sequentially discharges the output direction of the light-emitting element 105, and a relay lens. The illuminating element, for example, a light-emitting diode (LED) or a laser-emitting diode (LD), when the number is plural, can emit light of different wavelengths. Such as red, green, blue, etc., providing the light beam required by the projection system. In the present embodiment, the beam direction emitted by the crucible 101 is perpendicular to the optical axis 1, and is shaped and branched by the lens group 106 and the relay lens 107. Focus on. j Diwei's polarization splitting module includes a first-polarized light splitting surface for the first-polar light input and the second pole. The signal module 103 includes a first image unit (10) and an early image 10 (wherein the first image unit (10) is disposed on one side of the polarization beam splitting module (10), and 4 is located in the light source (four) line of the light source module 101. 'The secret of the first - the polarity of the wire with the image = in addition to the button (4).

After the light from the light source module reaches the first-polarized light splitting surface (10), the first-polar light reaches the reading list. (10); the light of the second polarity is reflected by the first polarization splitting surface (10) toward the second image unit 110. The light of the first polarity is converted into the second polar light carrying the image signal by the first German liquid crystal panel 1〇9. After that, it returns to the polarization beam splitting module ι〇2, and is reflected and converted.
