| 摘 要： | 在激光投影显示技术中,引入振动光纤的方法能够以较小的能量损失减弱激光散斑.本文利用广义范西特-泽尼克定理对激光投影显示中采用振动光纤抑制散斑做了理论分析.结果表明,散斑衬比度的大小取决于光纤的模式数和投影系统的光瞳大小,对于相同大小的像面,收集更多的光纤模式数和增大孔径均可减弱散斑衬比度.用两种不同的多模光纤所做的对比...

| Abstract: | In the laser projection displays technology,The method by vibrating the fiber can effectively suppress the speckle and reduce the light loss.Generalized van Cittert-Zernike theorem was used in the theoretical analysis of speckle reduction in the laser projection display,where the vibrating fiber was used as speckle reduction approach.The results show that the speckle contrast depends on number of optical fiber model and the projection system pupil size.For the same size of the image plane,more models of mul... |
