A polariscope is two polarizers that are turned so that they block the light from behind. Transparent items, especially plastics, exhibit color bands when they are positioned between the plates. These bands and fringes are interesting as they are, but can also be used as components in other digital creations, similar to the way flames are used to create “Fiery Effects”.
LCD displays have a liquid crystal fluid between two polarized plates. These plates can be removed and used to make a polariscope. You can also photograph the patterns by using just one plate along with a polarizing filter on the camera.
Step 1: Materials needed
Some single edge razor blades or thin knife blade.
Screwdrivers for removing the screen.
A light source to use with the polarizer screens. I used the screen of a discarded LED TV set.
Photo 1 shows the screen and the tools you need.
Step 2: Remove the screen
Photo 2 shows two screen assemblies, the front of one and the back of another.
Step 3: Separate the two polarizer sheets
Photo 4 shows how the sheets are held together by a white, rubbery, glue that needs to be softened by heat before you can insert a knife blade in there to separate the sheets.
Photo 5 shows how you slide a blade along the space between the sheets, being careful not to go too fast or separate them too far. It is easy to crack one of the glass polarizer sheets. The fluid between the sheets can be easily washed away once the sheets are separated.
