Figure 16: Images of two mirror system in LightTools. Image depicting the near-perfect irradiance output of the system. Figure 17: Two Mirror System in Code V To ensure that the system would produce an upright image, it was modeled in Code V. It was found that the only way to produce an acceptable image is for both mirrors to be angled at 45 degrees and parallel to each other. This configuration is shown below. This means a new location would have to be found for the periscope where the water is directly in front of the viewer. Figure 18: Image of two mirror system in Code V. This is the only way we can position the mirrors and still get an upright image. Figure 19: MTF performance of the two mirror system. As can be easily observed, the performance is diffraction limited. Figure 20: simulation for the two mirror system. Toroidal Mirror Option A slight variation to our two mirror system is to replace the upper flat mirror with a mirror that has curvature, specifically a toroidal mirror, which allows for different horizontal and vertical curvatures. This then provides our system with the added benefit of magnification and increased field of view. The toroidal shape allows for more of the horizontal view to be captured. This is ideal since we are trying to
