Abstract: Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images.

Abstract translation: 成形眼镜具有弯曲表面透镜和设置在弯曲表面透镜上的光谱互补滤光片，其被配置为补偿由于视角和其它光源而发生的波长偏移。 光谱互补滤光器包括保护带，以防止通过成形眼镜观看的3D图像的光谱互补部分之间的串扰。 在一个实施例中，光谱互补滤光器被设置在朝向透镜边缘的层厚度增加的弯曲透镜上。 投影的互补图像也可以被预先移位以补偿在观看图像时发生的随后的波长偏移。
