I question the feasibilty of recovering a high
quality image if no lens is used at all.
The Hubble case was a lens system that was
not focused correctly.
In any case, even zoom lenses are not very expensive. To achieve a usable
system in finite time, the plan of record would
logically include a commercial lens and image
sensor. The computational power behind those
minimal parts can do a lot of magic, witness the
cool results from the Frankencamera project,
which to my eye appears to be very open, and also
has some heavy muscles, e.g. Stanford & MIT.
What is the application goal of this project?
One assumes industrial grade security imaging?
It's certainly not a Copyleft Point and Shoot. ;)
