中文摘要
激光投影是投影机行业的一个技术趋势。与基于灯和led的传统投影仪相比,在投影仪中使用激光提供了相当大的优势,例如更长的使用寿命,更大的色域,更高的效率和更亮的照明。激光投影机被认为是新一代投影机,适用于数字影院、家庭影院和便携式显示器等各种应用。然而,由于激光的相干性,当激光从屏幕等粗糙表面反射时,会产生随机干涉散斑图案。激光散斑会降低图像质量
英文摘要
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
