Joy's talk
If anyone is in the Los Angeles area on Sunday December 16th, Joy is giving a presentation to Dorkbot ( http://dorkbot.org/dorkbotsocal/ ). She's the second speaker down the page. It's open to the public so anyone can attend.

Thanks Dinesh, We have two Polygrama guys in vacancy there so I may redirect them to something useful!
Sergio.

Sergio, I hope they come because It'll be good to meet some Polygrama people.
By the way, what did you think of the aberrations paper? ( http://www.triple-take.com/publications ... graphy.pdf ). Mostly, it's an overview of holographic aberrations from Meier and Champagne papers. Section 3 on resolution is my original contribution (although I don't think anyone noticed!). In the paper, I don't have experimental pictures, but I have pictures on the powerpoint ( http://river-valley.tv/aberrations-in-holography/ ) that show the effect of changing the convergence, angle and wavelength of the reconstruction beam.
By the way, these equations are based on thin holograms (Raman Nath regime), but Hariharan has a paper where he uses them to show something about longitudinal distortion in reflection holograms. It seems he is using the equations in the wrong regime!

Dinesh, I found it very interesting! Yes, I wonder how Harirahan used in volume and reflection holograms?!
Would be interesting and natural study volume holograms, however I foresee in my future use my holographic film volume space fitted with image plane composites of "photographs" so longitudinal distortion can be negligible (?) but the lateral one forming hogels aren't.
Forming very small composite elements maybe a problem with large film bandwidth reply. Ideally we need a computer trace software for the colour renditions.
