How about extending it to cover PST choppers (eg include an NXcrystal)?
(Or do we limit NXchopper to choppers which are strictly "absorb / not absorb",
to keep things simple?)
Another approach would be to treat a PST chopper as "rotating crystal(s)".
(I got also told that there are other applications of rotating crystals.)
To describe a rotation, one could extend NXgeometry, or invent a separate
class. Even better would be to allow other types of movement too -
thinking of the Doppler mirror in backscattering instruments.

best regards
