摘要： Systems and methods configured for outputting light having a polarization state distribution that is spatially uniform by applying a correction to, for example, a beam of light with a spatially uniform polarization state distribution that has been altered (unintentionally or otherwise) to become spatially non-uniform are described. A projection system can include an optical element and a polarization-altering device (PAD). The optical element can cause a polarization of light in the projection system to be spatially non-uniform. The PAD can change the polarization state distribution of the light spatially based on an amount of spatial non-uniformity on the light caused by the optical element and before the light enters the optical element. The projection system can output the light having a spatially uniform polarization state distribution.

摘要： A system for motion control is presented. In one embodiment, a motion control 3D projection system includes a projector; and a projection surface coupled to a robotic arm, where the robotic arm moves the projection surface through a set of spatial coordinates, and a 3D projection from the projector is projected onto a set of coordinates of the projection surface and matches the 3D projection to the set of coordinates of the projection surface as the projection surface moves through the set of spatial coordinates. In additional embodiments, a master control system may integrate additional robotic arms and other devices to create a motion control scene with a master timeline.

摘要： A system projects a user-viewable, computer-generated or -fed image, wherein a head-mounted projector is used to project an image onto a retro-reflective surface, so only the viewer can see the image. The projector is connected to a computer that contains software to create virtual 2-D and or 3-D images for viewing by the user. Further, one projector each is mounted on either side of the user's head, and, by choosing for example a retro angle of less than about 10 degrees, each eye can only see the image of one of the projectors at a give distance up to 3 meters, in this example, from the retro-reflective screen. The retro angle used may be reduced with larger viewing distance desired. These projectors use lasers to avoid the need for focusing, and in some cases there projectors use instead of lasers highly collimated LED light sources to avoid the need for focusing.
