Abstract: A structure of an ultraviolet light polarization component and a manufacturing process thereof, where a multi-layer thin film structure set is plated on a transparent falt substrate, and the multi-layer structure setis composed of a low refractive index thin film layer stacked for N times and a high refractive index thin film layer. The violet light is polarized into two polarization lights through the ultraviolet light polarization component, in which the two violet lights have a polarization ratio of larger than 10, so that the technical efficacy of realization of a small volume optical component and a large incident angle of the ultraviolet light.

Abstract: An apparatus for reducing laser speckle cooperates with a laser light source and comprises a light guide tube and a vibration element coupled on the light guide tube. The light guide tube includes an input member corresponding to the laser light source, an output member far away from the laser light source, and a chamber allowing a laser beam which is emitted by the laser light source to perform total reflection inside. The vibration element is arranged at a region between the input member and the output member to drive the light guide tube to vibrate reciprocally along a direction not parallel to the axis of the light guide tube. The vibration element controls the light guide tube to perform swift, reciprocal and high-frequency vibration to destroy coherence of the laser beam. Thus the laser beam can be output uniformly to avoid laser speckles caused by light interference.

Abstract: A diffraction-type 3D display element is arranged on an image output face of a 3D display device and comprises a first diffraction area and a second diffraction area. The first diffraction area has a plurality of first stepped gratings spaced apart from each other. The second diffraction area has a plurality of second stepped gratings spaced apart from each other. The second diffraction area is adjacent to the first diffraction area and is arranged symmetrically to the first diffraction area with a central line being the symmetric axis. The diffraction-type 3D display element of the invention diffracts the images output by the 3D display device and projects the diffracted images to two different viewing areas to provide 3D images for users.

Abstract: The present invention discloses a 3D image capture device and a symmetric prism array for the same. The symmetric prism array comprises a plurality of right triangle prisms, wherein the longer legs of the right triangle prisms are arranged along an identical line on the incident plane, and wherein the right triangle prisms are left-right symmetric with respect to a central symmetry line, and wherein the normals of the hypotenuses of the right triangle prisms diverge from the central symmetry line. The symmetric prism array that captures light from two different directions is arranged in front of the lens of the 3D image capture device, whereby the 3D image capture device can capture images from two different directions simultaneously. After the image processing by the 3D image capture device, 3D images are presented.

Abstract: An auto-stereoscopic multi-dimensional display component is applicable for receiving and splitting a backlight source into waveband lights, and the waveband lights can be refracted to different positions of colored pixels. The multi-dimensional display component comprises a color grating element and a light guiding element; wherein the color grating element is configured to split and refract the backlight source, while the light guiding element emits the waveband lights towards the corresponding pixel positions. When the auto-stereoscopic multi-dimensional display component is applied in an image display device, it becomes a device of different dimensions according to its spectroscopical position.
