Craig
you are correct.
Currently the PARISS only detects X-Y--not depth.
however, most data that I have seen from confocal spectral systems are
only a single XY slice. they usually are not used to do a 3D
reconstruction in spectral mode.

It doesn't seem to deal with depth though? It only detects in X-Y, so
can it generate optical slices?
