There is a paper about this lens in the latest proceedings of the
Stereoscopic Displays and Applications Conference.  "Parallax Scanning Using
a Single Lens" Chistopher Mayhew & Aron Bacs Jr. in "Stereoscopic Displays
and Virtual Reality Systems III" Proceedings of the SPIE vol. 2653 
pp154-160.  Check out "http://info.curtin.edu.au/~iwoodsa/spie96" for
info about that conference.  The contents page and preface are online.
