Laser projection system suitable for commercial motion picture theaters and other large screen venues, including home theater, uses optical fibers to project modulated laser beams for simultaneously raster scanning multiple lines on screen. Emitting ends of optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more scan lines apart. Use of optical fibers enables scanning of small, high resolution spots on screen, and permits convenient packaging and replacement, upgrading or modification of system components. Simultaneous raster scanning of multiple lines enables higher resolution, brightness, and frame rates with available economical components. Fiber-based beam coupling may be used to greatly enhance the flexibility of the system. Alternate embodiments illustrate the flexibility of the system for different optical fiber output head configurations and for different types, sizes, and arrangements of laser, modulation, and scanning components.

The present invention relates to a method for preparing stable speckled bricks. The preparation method includes: (1) green body pressing: white spots proportioning 5-10%, blue spots proportioning 10-20%, black spots proportioning 70-80%; (2) green body drying: temperature 80-130°C, time 40 to 60 minutes; ⑶ Simulation processing: apply a translucent glaze layer on the surface of the body, and then use inkjet printing to print inkjet false spots that are close to the size and color of the spots on the body. The color and spot effect of the translucent glaze are consistent with the body. The color and surface effect are basically consistent; ⑷Printing and decoration; ⑸Applying protective glaze: After decorating the color and pattern effects through screen printing, rubber roller printing or inkjet printing, apply transparent glaze slurry to protect the decoration, so that the spots can sink under the glaze layer , achieving highly simulated fusion with the spots on the green body itself; ⑹ Firing: temperature at 1150~1250℃, time 40~60 minutes.
