A projection apparatus comprising a prism assemblyincluding an input sub-prismpossessing a first interface surface and an output sub-prismadjacent to the input sub-prism possessing a second interface surface. The second interface surface is spaced from the first interface surface immediately proximate to it and extends over it to receive display lighttransmitted through the first interface surface. A panelcomprising a plurality of selectively adjustable reflecting elements is arranged to receive from the input sub-prism an illumination light totally internally reflected from the first interface surface and selectively to reflect received illumination light back through the input sub-prism for transmission through the first interface surface for receipt as display lightby the output prism at said second interface surface.
