-This is a fairly advanced tutorial, you will need some rudimentary knowledge of photoshop. This tutorial also uses Adobe Imageready, but don't worry it comes free with photoshop. Disclaimer stated, this is a cool effect and if you follow my instructions you should be able to duplicate it.

-Make a new layer by clicking on the New Layers button

-and then double click on the layer, call it Metal

-Go to Filter>Render>Clouds

-Then Adjust the Brightness/ Contrast like this (Image>Adjustments>Brightness/Contrast...

 

-Next go to Filter>Noise>Add Noise...

-Now go to Filter>Brush Strokes>Angled Strokes... with these settings:

Direction Balance: 37

Stroke Length: 23

Sharpness: 3

-To make this tutorial a manageable length I am doing the first part for you. I need you to download my pattern set.

Here

-Download it and place it in your Adobe\Photoshop \Presets\Patterns folder. Then go back to Photoshop and go to Edit>Preset Manager...

-Then in the Preset Type dropdown menu select Patterns, Hit the load button, and load the Mypresets.pat file

-Complicated already, I know.

-Now Select the Paint Bucket Tool and change the fill option to pattern as shown in the image. Select the pattern I have surrounded by red.

 

-Now In the Layers Palette click on the Channels Tab and hit the New Channel Button.

-Now Fill the new channel Alpha 1 with the pattern we just selected.

-Hold Ctrl and click on Alpha 1 in the Channels Palette.

-Now click the Layers Tab in the channels tab and and click on the Metal layer.

-Hit backspace to erase the selection, then ctrl + D to deselect.

-Now apply this layer style

-Now its time to think about what text you want to appear when the scanner goes over it. Erase one hexagon for each letter. I used the Polygonal Lasso Tool to do this.

-Confused? If your image doesn't look like the one to the right (or something similar) you might want to go over the instructions up to this point again.

 

-Now it really gets complicated. Its time to discuss the theory behind how this works. Basically we have a rectangle (our viewable image). Now there are 2 "wings" attached to our scanline that travel with it. These wings cover up the text when the scan line isn't directly over it. They are on seperate layers, but they are linked so they move together. Understand?
