Deimos.
To make the lines do the following:
File: New
Height 5px & Width 5px
Then Click (Fit on screen)
Take your pencil tool and make it 1px
Use Blk or a Dark Color
And start making a diagonal line like this:
Then click Edit > Define Pattern > Name it: Scan Line
Now Create a new layer:
Select your Pattern Stamp Tool
Select the Scan Line pattern from the list
Then use a brush tool and paint the pattern onto of the layer you just created.
You'll have to adjust the Opacity to like 20 - 40.
