摘要
目前大多数眼跟踪器体积大、质量重,影响人机工效。采用全息波导技术解决这一问题,将全息波导元件应用于眼跟踪系统,设计了一个全息波导眼跟踪光学系统,探测眼部红外图像。介绍了基本设计原理、分析了光学系统像差校正及眼部照明方法。仿真计算结果表明,该红外探测眼跟踪光学系统像差小,可以较好地成像在红外CCD相机感光面上,使探测到的眼红外图像能较好地反映实际的眼部图像,从而有利于依据算法提取眼部数据,提高眼跟踪系统准确性,并且整体质量轻、结构紧凑。
Most of the eye-tracking systems are heavy and bulky,which has a negative effect on man-machine efficacy. Thus we used waveguide holography to solve the problem. A waveguide holographic eye-tracking optical system was presented for detecting the infrared image of eye. In this paper, the prime design principle was introduced, and the approaches for aberration correction and eye illumination were analyzed. The simulation result showed that： 1 ） this eye-tracking optical system has small aberration ;2） a relative ideal image could be obtained by CCD camera,which could deliver more actual information of eye movement and improve the detection veracity by using the data obtained through image processing algorithm. The analysis shows that the waveguide holographic eye-tracking optical system has low aberration, light weight and compact co/Lformance.
