Abstract:
1. A prism assembly, comprising: a set of beamsplitters including a set of modulating faces and configured to, separate an input light beam into a set of component light beams, direct each component light beam to a corresponding one of a set of modulating faces of the prism assembly, and recombine light beams reflected from the modulating faces into a modulated output beam; a planar optical component; and an internal frame coupled to the planar optical component and configured to position the planar optical component in a channel, the channel being defined between a first face of a first beamsplitter of the set of beamsplitters and a second face of a second beamsplitter of the set of beamsplitters, wherein the first face is adjacent to the second face, wherein the planar optical component is positioned in a rectangular cone of the at least one of the component light beams passing through the channel and wherein the channel orients the planar optical component relative to the first face and the second face, wherein the channel is filled with an optical coupling liquid, wherein the prism assembly comprises a quad style prism assembly comprising 4 beamsplitters and the internal frame comprises a set of two internal interdigitated dual frames configured to place the planar optical component in each of 4 channels between adjacent faces of the beam splitters.
