Knowing the polarization of light is essential for many optical systems and experiments. The issue is not the availability to a quality polarimeter, but rather the cost and mobility of it. By implementing a Raspberry Pi both of these problems are resolved effectively. The size of the Pi allows for the entire polarimeter to be no larger than 7in in length and 4in in width. With an easily attachable high resolution camera, multiple USB ports, and price it makes the Raspberry Pi an ideal candidate for this project. Furthermore by using a Pi streamlines the construction process as it has no moving parts, and allows for an overall simpler design without compromising functionality. By utilizing Savart plates, and the Raspberry Pi camera, four images can be created denoting the intensity of the beam, its horizontal, vertical, and/or circular polarity. With the code that is being implemented also being fairly flexible the same device can be used for an uncoupled beam profiler. Having a polarimeter and beam profiler in one compact and cost effective unit makes this tool ideal for smaller optical laboratories.
