At this point, everything is set up. All that's left is for me to actually figure out how everything works.
- 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
- Great theory resources here when it comes to PEM operations http://www.hindsinstruments.com/knowledge-center/product-document-library/product-literature/
