Dear Christophe,

The short answer is:  yes, it could be used for your Z-stacks,
and no it is not a totally different kind of deconvolution.

The long answer is harder to explain.  There is just one definition of
deconvolution, but there are a lot of different methods that can be used
to actually do the deconvolution. Furthermore, some people use different
names for essentially the same methods. Why different methods? That's
hard to explain without using a lot of mathematics. The basic idea is that
the result produced by deconvolution algorithms depends on the image, the
noise in the image, and the PSF. One deconvolution method might work well
for one problem, but not so well for another problem. So it is good to
try different methods. This plugin uses fairly standard deconvolution
methods, with two advantages. First, we provide different deconvolution
methods that you can try with your data -- maybe one will work better
than another. Second, our methods have been implemented to be very
efficient on modern multi-core processor machines.
If you want to know more about these algorithms, I recommend an excellent
book: "Deblurring Images: Matrices, Spectra, and Filtering" by
Per Christian Hansen, James G. Nagy, and Dianne P. O'Leary, SIAM 2006.
