电致变色膜改善穿透式视频眼镜对比度的方法
A method on improving the contrast of see-through video glass
摘要
穿透式视频眼镜在日常使用中普遍存在对比度不高,成像效果不理想的缺点。依据电致变色膜加电状态下能够削减环境光的原理,对穿透式视频眼镜的对比度进行改善。通过TracePro软件光学仿真及成像亮度计进行实验验证,对EPSON BT-200穿透式视频眼镜进行测试和分析,验证该方法的可行性。实验数据与实际视觉观测结果基本相符,表明了这种方法的正确有效。
Abstract
See-through video glass in the daily use has shortcomings of low contrast and non-ideal imaging results.This paper improves the contrast of penetrating video glasses based on the principle that the electrochromic film can be used to reduce the ambient light.Electrochromic film is a specific device based on electrochromic principle.Experiments were carried out by using TracePro optical simulation and imaging luminance meter.The EPSON BT-200 penetrating video glasses were tested and analyzed to verify the feasibility of the method.The experimental data are in good agreement with the actual visual observations,indicating the correctness of this method.
