Linearly polarized light whose Jones vector is ( 1 0 ) (horizontally polarized) is sent through a

train of two linear polarizers. The first is oriented with its transmission axis at 45 degrees and

the second has its transmission axis vertical. Show that the emerging light is linearly polarized

in the vertical direction. Discuss the intensity change through each polarizer

Solutions

Expert Solution

a) the vector Jones is

The first polarization is defined by the Jones matrix with an axis of transmission at 45 degrees

and the second polarization of the light is defined by the Jones matrix with an axis of transmission vertical

This shows that emerging light is linearly polarized in the vertical direction

b) If the initial intensity is

the intensity after light passes through first polarizer is

and the intensity after light passes through second polarizer

hence, the change of intensity is

The change of intensity is negative because the intensity of the light decreases after passing the polarizers

A particular beam of light, with an intensity of 440 W/m2, is linearly polarized at an angle of +5.00° to the vertical. You have three polarizers, which have their transmission axes aligned as follows: Polarizer A - the transmission axis is at +19.0° to the vertical; Polarizer B - the transmission axis is at +72.0° to the vertical; Polarizer C - the transmission axis is at +25.0° to the vertical. You will select two of these polarizers, and have the...
