Interference Pattern Structured Illumination Imaging (IPSII) utilizing Mach-Zehnder Interferometry, allows us to surpass the Abbe Limit of traditional imaging techniques. To aid in this endeavor, my primary objective is to utilize a Michelson-Morley Interferometer with one of the arms being a long-distance, 300mm or greater, linear translation stage. Using the long-distance linear translation stage (LDLTS) to test both the repeatability and as well as angular stability of various LDLTS units so we may take measurements of fringe lines at arcseconds approaching a zero degree of angle. Though many designs currently available for consumer use have the linear repeatability needed, most if not all lack the angular stability needed. As such we are currently experimenting with current designs to see where the variances are and work in improvements so we may design our own LDLTS so we may be able to take such extreme angle measurements. In addition to improving the repeatability and angular stability of LDLTS's, the automation of the kinematic mirror mounts utilizing stepper motors is another primary concern. Our current issue is that we need to be able to adjust the reflecting mirrors on both the x-axis and y-axis and to do this the stepper motors need a travel distance of 27mm along the z-axis. The issue we have is we need a stable mount that addresses any torque lash while keeping them still and allowing movement on the z-axis. Through materials research for what to be used with the LDLTS as well as the stepper motor mounts, we will be able to take data points and processes data at a much greater and more accurate rate than we have in the past. Resulting in more time to conduct experiments and less time waiting for results.
