Today, Peter came back. In the morning, we worked on testing the camera pixels to see what pixels measure vertical, horizontal, 45 degree, and -45 degree polarized light. We had to use a polarizer, but before we used it, we had to figure out its orientation of by using a wollaston prism, which splits unpolarized light into horizontal and vertical polarized light. Lee helped us figure out how to use the prism and the polarizer, and we found that at 0 degrees, the polarizer created vertically polarized light. We then took pictures using the CCD camera of a white background inside the polarizer at different polarization states (0 degrees (vertically polarized), 45 degrees, 90 degrees (horizontally polarized), and 135 degrees (-45 degrees)), and analyzed which pixels allowed light through. If a pixel shows up white, that means that the pixel measures light at the polarization state of the polarizer. For example, when the polarizer was set for 90 degrees, the pixel that appeared white meas...
