I doubt Canon would release these. And I also doubt anyone would be able to reproduce something such as this, unless they\'re willing to dissect a lens and do a TON of work. You\'d have to go to Canon to get a bunch of details about lens construction that I\'m betting they wouldn\'t disclose.
Also - the light doesn\'t turn upside down, the sensor records a virtual image.
it\'s not a big secret in the general sense you can just ray trace through their diagrams, although they are so complex it would be a major PITA
as for trade secrets they already publish the diagrams, of course they are not manufacturing level detailed and you could always slice a lens in half and carefully measure each element and test the composition
of course you still need to be able to manufacture precisely and make each type of glass element and carve and polish them etc.
