At this point, everything is set up. All that's left is for me to actually figure out how everything works.

Here we see the two lock-in Amplifiers, the Single Conditioning Unit, the PEM modulator, and a digital Multimeter.
  • We decided to initially go with the polarizer-foil-pem-analyzer-diode set up. (there is an alternate setup in the PEM manual in section 3c)
  • The above setup reports Kerr rotation and ellipticity. Whereas the chapter 3 section c only reports a Kerr rotation.
  • We learned that 2 Lock-in Amplifiers are necessary in order to lock on to two different frequencies
  • The lock-in Amplifier reports V(rms) as opposed to a peak Voltage
