We report the capture of images via a wedge light-guide without the margin for fan-in needed heretofore. While this lets one look out of a slim panel as if it were a periscope, half the power is lost and resolution is degraded by aperture diffraction. Volume gratings may resolve these drawbacks at certain wavelengths and we consider how these might be extruded.
