I have been told that confocal-like images with optical sectioning
capability can be obtained without using laser confocal microscope hardware.
One obtains images using a standard microscope and ccd camera as one steps
along in z (ie numerous changes in focus).  These blurred images are
processed together along with the point spread function for the optical
system to produce in-focus images at the numerous z-planes.  Can someone
tell me:

1.  Where I can find a good description of this approach.
2.  Where I can obtain (free? buy?) the deconvolution algorithm.
3.  If there is an accepted name for this approach.
4.  What are the tradeoffs between the hardware and software approaches
        in x, y and z resolution and acquisition time.

Thank you in advance for any asssistance
