| Abstract: | Laser speckle reduction is an important research topic in laser display, and laser speckle problem is a key problem of blocking the laser display real practical application. In the paper, it summarizes the merits and feasibility of speckle reduc- tion schemes, and focuses on the analysis of the reduction scheme by dual screens shaking. On this basis, it put forward three kinds of speckle reduction schemes： speckle reduction by ferroelectric liquid crystal; speckle reduction by waveguide disturbance fiber and rotating diffuser speckle reduction. |
