Autostereoscopic Front Projection System Based on Micro-Lenticular Lens Array
摘要
Abstract
The principle of autostereoscopic front projection display based on micro-lenticular lens array is introduced. Formulas to determine the parameters of the micro-lenticular lens are deduced and a method to design the micro-lenticular lens array is proposed. A piece of stereoscopic projection screen is designed based on the method and the whole projection system with the screen is emulated in Lighttools. The simulation result shows that there are five definite viewing zones. The distance of the adjacent viewing zone is very close to each other. The projection system is built up and the observe plane is at the vertical plane with the projectors. The crosstalk is 7. 9% and overlap ratio is 1. 008. The final result is consistent with the simulation result and the autostereoscopic display effect is good. The experimental results show that the autostereoscopic front projection display based on micro-lenticular lens is feasible. Compared to autostereoscopic rear projection, the autostereoscopic front projection display has the advantages of simple implementing, compact structure and adjustable projection distance, therefore it will be an important developing direction of large screen 3D display in the future.关键词
