Create a New Document that is 1 pixel by 2 pixels....



Zoom in and color the top pixel black....



Choose Select > Select All from the menu.

Then choose Edit > Define Pattern from the menu and save the pattern. You can then close the new document and there's no need to save it. It is merely used to create the pattern.

Now, go back to your original image and add a Pattern Overlay Layer Style to any layer you wish to have the lines on....



You can then adjust the blending mode or opacity to your liking.

There are literally thousands of tutorials online for this if you merely search for "scan lines Photoshop tutorial".

For illustrator it's pretty much the same idea.. overlay a pattern of horizontal lines. Illustrator does ship with some default line patterns though Patterns > Basic Graphic Pattern > Basic Graphic Lines from the Swatch Panel. So, there's no need to create your own pattern.
