摘要： Compact beam manipulators employ one or more Risley prism sets with or without a parallel plate translator. One beam manipulator contains a plate mounted to permit pitch and yaw adjustments and a prism set mounted to permit rotations. The rotations of the prisms adjust a beam direction, and adjustment of the plate adjusts the beam position. Another beam manipulator contains a prism set mounted to permit rotations and pitch and yaw adjustments of the prisms. The rotations and pitch and yaw adjustments provide coupled changes in the position and direction of a beam, and iterative adjustments alternate between rotating prisms to change the beam direction and the adjusting pitch and yaw to change the beam position. The iterative adjustments are complete when the beam has a target position and a target direction to within required tolerances. Gluing elements to optic holders minimizes stress-induced birefringence and temperature and humidity effects.

摘要： A frame, termed a prism frame, is attached to a processing face of a prism assembly and used to hold a position of a compensating waveplate and a microdisplay. The compensating waveplate includes adjustment tabs that allow precise positioning of an orientation of the waveplate (e.g., waveplate angle, rotation, etc) such that it is best positioned to compensate for items like residual retardation and/or skew rays that occur in the kernel. The precise position is varied depending on kernel design and other factors. A microdisplay frame is attached to a microdisplay package. The microdisplay frame is then precisely attached to the prism frame. The microdisplay can be removed from the kernel by sacrificing the inexpensive microdisplay frame.
