Here is a USN test pilot from VX-23 at Pax River describing how the BEDFORD ARRAY may be used on CVNs in future (which method applies to SRVL to CVF approaches).... [References to Fig.1 & 2 are to the combined graphic as shown attached.]

"...-“...We may also need to add another lens-type glideslope indicator. One idea is called a Bedford Array. You can see in Figure 1 that a Bedford Array is like a lens spread of over the length of the LA. Unlike an IFLOLS which has 12 cells that are always on to create a glideslope reference, the Bedford Array is a set of Christmas lights and only the light corresponding to current position of the touchdown point is illuminated. Just as the dynamic touchdown point moves across the deck on the LSODS screen, the Bedford Array lights would “move” forward and back across the deck corresponding to the dynamic touchdown point. Figure 2 shows what your HUD may look like. You keep the ship stabilized velocity vector on top of the Bedford light that is illuminated. The datum is a reference line in your HUD. As long as the 3 all line up you are on glide path. A Bedford Array & a ship stabilized velocity are indicators of glide-slope that will show you if you are off glide-slope more precisely but they still don’t make the airplane respond differently....”
