Abstract: A computer-implemented method may include (1) causing a radar component to emit one or more radar signals and (2) causing the radar component to analyze one or more return signals. Also disclosed is a method for forming a 3D liquid crystal polarization hologram optical element and a method for characterizing diffractive waveguides includes directing light onto a structure and measuring the diffracted light to capture at least one image of the structure. Lastly, disclosed is a method of pattering organic solid crystals and a method directing a beam of input light to a surface of an optical material to determine crystallographic and optical parameters of the optical material. Various other methods, systems, and computer-readable media are also disclosed.
