A method of speckle suppression without any active device is expected for pico-projectors. The effectiveness of the passive method of speckle reduction using a single multimode fiber and a multimode fiber bundle was actually measured and theoretically analyzed. The dependences of the speckle contrast and speckle suppression coefficient on the parameters of multimode fiber and projection systems were investigated. Our results shown that the efficiency of speckle suppression was limited because only the radial direction of the objective lens aperture was used. An improvement using both of the radial and azimuthal directions of the objective lens aperture is required.

通过使用无源多模光纤和多模光纤束来研究超出人眼灵敏度的斑点抑制

对于微型投影仪,期望一种没有任何有源设备的散斑抑制方法。实际测量和理论分析了使用单条多模光纤和多模光纤束的被动去斑方法的有效性。研究了散斑对比度和散斑抑制系数对多模光纤和投影系统参数的依赖性。我们的结果表明,由于仅使用物镜孔径的径向方向,因此斑点抑制的效率受到限制。需要使用物镜孔径的径向方向和方位角方向的改进。
