New Circuit for LRL

[sharky]

Does anyone have this Target Sample Fed LRL

I know one guy who uses LRL, in it he keeps one ampule containing diamond in each of the Lrl and it detects diamond, gold ampule and it detects gold, a photo of person and the rods move across the person thus detecting him. The shape is 2 L rods and it has got some circuitry, and these L rods move across when a target is found, can anyone have this Target sample Indentifying LRL circuit or can anyone explain how this works. I have put an edited image from an existing LRL to look just like this( to get an Idea) for feeding the ampule and a switch for both rods and 1 led on each rod.
