光学自由曲面高性能头盔显示器中的关键问题研究

In-depth study of the critical scientific problems of the high performance Head-Mounted Display (HMD) will be carried out in this project. It is difficult to achieve wide angle and high resolution in an HMD simultaneously, and accommodation and convergence mismatch problem is the second serious issue that we are concerned in a stereoscopic HMD. In order to significantly reduce the size and weight of the high performance HMD, we proposed the optics tiling and multifocal plane HMD solutions both based on the freeform optics to the two problems that we pinpointed and concerned, respectively.The description and optimization method of a freeform optical system that used in the high performance HMD will be investigated, the tolerance analysis based on the fabrication and assemble procedure is implemented to guide the further optimization of optics used in the high performance HMD. The calibration and image rendering technologies that for a high performance HMD will also be studied, these including the none-slot merging and the depth-fused rendering techniques. The performance and comfort of the HMD will be tested through the objective and subjective experiments. Key technologies of the high performance HMD with international advance level will be mastered and the high performance HMD products with proprietary intellectual property rights will be developed. It has important theoretical value and broad application prospects.
