Please give me a clue about how this aparatus works. You cannot use curved
mirrors alone, since they are a priory not perfectly curved.
And if you have figured out how you can turn a diffusive beam of light into
a parallel beam using mirrors only, I'm very interested since that would be
worth some money.
Brian.
You are right. We would have to run the beam through a lense that would
bend the beams to parallel vectors. Found that out just thirty minutes ago.
Not going to be easy to accomplish on a retro mirror if wavelengths tend to
change through doplar shifts
NOTE TO GROUP: I have to go now but I wanted to forwarn you about a
conclusion I had about this whole retro-mirror, light-sail propulsion,
automotive technology problem. Its coming tomorrow so get ready for me to
slam the hammer down. (hint: I plan on breaking a lot of unneeded
glass/plastic mirrors, etc. and completely rewriting the mission
definition). Got to go to class. RIGHT NOW!
