Abstract: A speckle damping system for dampening speckle on a projection screen for a projection display system employing coherent or partially coherent light sources (e.g., lasers, LEDs) are disclosed. In one embodiment, a rotatably coupled system is disclosed, comprising: a set of actuators; a set of rotatably coupled mounts, each of said set of rotatably coupled mount capable of mounting at least one said actuator; and wherein said at least one actuator mounted on said rotatably coupled mount is in moveable mechanical communication with said projection screen. In another embodiment, a linearly coupled system is disclosed comprising: a set of actuators; a set of linearly coupled mounts, each of said set of linearly coupled mount capable of mounting at least one said actuator; and wherein said at least one actuator mounted on said linearly coupled mount is in moveable mechanical communication with said projection screen.

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: Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D 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。
