How polarizers can remove surface reflections?

There is simple method of using two perpendicular polarization films. The angle on which light should fall is called Brusters angle. This is an angle when incident polarized light is turned 90 degrees when it is reflected.

The system of imaging looks as follows:

And here you can see a results where photos are made with polarizer system and without it.

1) Without polarizers:

glossy

2) With polarizers:

As you can see, using two perpendicular polarizer filters remove surface reflections that gives better view of skin structure. This is handy procedure for images being processed digitally.

One Comment:

  1. Brewster’s angle (also known as the polarization angle) is an optical phenomenon named after the Scottish physicist, Sir David Brewster (1781–1868).
