Laser projection is a technology trend in the projector industry. The use of lasers in projectors provides considerable advantages as compared to the traditional projectors based on lamps and LEDs such as longer life time, larger color gamut, higher efficiency and brighter illumination. The laser projectors are considered to be the next generation projectors for various applications such as digital cinema, home theater and portable display. However, due to the coherent nature of lasers, random interference speckle patterns will be generated when laser lights are reflected from a rough surface such as a screen. Laser speckle degrades the image quality

激光投影是放映机行业的一种技术趋势。与基于灯和LED的传统投影仪相比，在投影仪中使用激光具有更长的寿命、更大的色域、更高的效率和更明亮的照明等优点。激光投影仪被认为是用于数字电影、家庭影院和便携式显示器等各种应用的下一代投影仪。然而，由于激光的相干性质，当激光从粗糙的表面(如屏幕)反射时，会产生随机干涉斑纹。激光散斑会降低图像质量
