Schlieren imaging is a technique for visualizing fluid flows that are characterized by spatial variations in density or refractive index. Because schlieren imaging is commonly performed with expensive equipment in a lab setting, we sought cost efficiency, accessibility, and ease of fabrication by designing a portable, smartphone-based system.

Understanding magnetic properties of materials allows for advances in applications such as data storage. The Magneto-Optic Kerr Effect (MOKE) displays the reflective response a magnetic material has to a magnetic field. When polarized light reflects off of a magnetic material, the polarization orientation can change. The application of an external magnetic field can affect how much this polarization changes in a non-linear manner. Hysteresis loops are created when examining the relationship between intensity of the reflected light to the applied magnetic field provide information about magnetic properties of that material, such as the coercive field and field retention. Preliminary measurements …
