Reflection, Transmission and Fresnel’s Coefficients (3.1)

Student's Manual The reflection and transmission of light from a dielectric medium (for example glass) shows fascinating properties such as Brewster's angle. This experiment explores the relation between Fresnel's Coefficients, the Brewster angle and the refractive index of the glass.
Matlab Simulation reflectance
Sample Results Reflectance curves

Diffraction from Single and Double Slits (3.2)

Student's Manual Diffraction is one of the remarkable consequences of the wave nature of light. In this experiment you will study diffraction patterns for single slit and double slit arrangements. Furthermore you will explore techniques in image analysis for quantitative evaluation of the phenomenon.
Simulation diffraction
Matlab Files Single and Double Slit Diffraction
Sample Results Single Slit, Double Slit

Investigating Polarization of Light through Jones Calculus (3.3)

Student's Manual Polarization is one of the fundamental properties of light. The purpose of this experiment is to get familiarized with the polarization of light as well as effects of different optical components on it.
Sample Results Polarized Beam Splitter, Quarter Wave Plate

Analyzing the Polarization State of Light through the Fourier Series (3.4)

Student's Manual One can completely determine the polarization of light simply by using a polarizer and a quarter wave plate. In this experiment you will develop a method to generate as well as analyze different polarization states of light.

Investigating Longitudinal Laser Modes using a Scanning Fabry-Perot Interferometer (3.5)

Student's Manual The Fabry-Perot interferometer is an optical instrument which uses multiple-beam interference. In this experiment we will learn to characterize the interferometer and use it to diagnose the longitudinal modes of a HeNe laser.
Simulation Cavity Transmission
Sample Results Cavity Transmission Plot, Cavity output on oscilloscope
