If you place a mirror flat against a flat surface, and position said
mirror in the center of the frame and position your lens reflection at
the center of the mirror, you're at the correct alignment to shoot the
flat surface.
The moment you see your reflection you're very close to being 90 degrees
to the mirror plane. Placing the mirror in the middle of the frame and
then seeing your image in the middle of the mirror is going very, very
close to exactly 90 degrees to the mirror - and any flat surface against
wich the mirror is paralel.
You may use a strong flaslight, if your mirror is too small or farther
away - you should see the light reflected back to the flashlight the
moment it is 90 degrees to the mirror. No laser - you really don't want
to look into a laser.

I need to experiment with this. I can't visualize how a mirror helps
to align the ccd and the wall.

flat mirror with the back to the wall in the center of the frame to make
sure you're properly aligned.
