Document Summary
Tutorial-5-solutions: let the irradiance of the input light, the light through the rst polar- izer and the light through the second polarizer be represented by io, i1, i2 respectively. I1 = io cos2 (40 10 ) = io cos2 (30 ) I2 = i1 cos2 (60 10 ) = io cos2 (30 ) cos2 (50 ) = 0. 310io: let the irradiance of light emerging from the rst, second and third polarizers be represented by i1, i2, i3 respectively. Figure 1: an optical system composed of two quarter wave plates and a linear polarizer. a). Input: x polarized light. (we have dropped the exponential term for the quarter wave plate for the convenience, as it only changes the magnitude) Thus the output is right hand circularly polarized light with transmit- tance of 1. Output is right circularly polarized light. (iv) .
