Please cite your reference for this 'conjugate mirror'.


In "Reflections", Walt has a chapter entitled "Into the
Conjugate Mirror" or something like that.

I'm hoping to buy the third edition. The reason I asked is because the
only thing I can find is something called a phase conjugate mirror,
which has some really interesting behavior. And not exactly the
behavior being discussed in this thread. Time reversal for example.
For starters, check out:

I doubt Richard had considered all the possibilities when he said to
elaborate would be redundant.
