Is anyone in this group familiar with lasers?
Just asking, what about a projection hologram of a cylinder, would that achieve the effect you desire?
Also, when one reads a book on T-lines, at the end, they say something like this only describes the lowest-order transverse emission mode. Can someone elucidate the other TEMs?
