beam movement

Dear Sir,

I would be grateful if you could give me some tips on how to solve this problem-


A parent laser beam must be split in to 2 daughter beams, which must be steered in opposite direction.
I can use a scanner to scan one of the daughter beams.
The other daughter beam must move in exactly opposite direction.

I do not want to use another scanner for this daughter beam, how can I scan it using beam splitter or a prism etc?


Regards

We need lots more info. This doesn't make any sense.
What will you be scanning and why? What scan pattern? Why two different directions? What's your budget? What laser are you working with? Throw us a bone here.
