Hello
One quick question about bi and mono directional scanning in confocal 
microscopy. In mono directional scanning, what happen to the laser light when 
the galvanometer mirror brings the beam back to the beginning of the line? My 
understanding is that it does not reach the sample if the system is equipped 
with an AOM or EOM, but I am not absolutely sure about why. And what 
happens during a dual color bidirectional scan?
Thanks a lot!
