Twenty-second Day


On Friday, the Undergraduate Research Symposium was happening on campus, so Tristan, Peter, and I went to a couple of presentations. One was about quantum dots being used on sensors, and the other was Lee's presentation about polarized cameras.

In the afternoon, Peter and I continued to work on our code in MATLAB. Through our code, we are able to average information from a file folder full of pictures, and then measure the Stokes parameters from the average data. We took some more pictures of skin, and realized that the skin has to be pretty uniform in color for taking pictures, or else the camera creates false polarization. What this means is that in order to take a picture of a darker area of skin, such as a mole or scar, the camera will have to be zoomed in to just that darker area of skin; lighter skin that surrounds the darker skin cannot be in the photo or else the data will be incorrect.

Second Day

Day 2 of interning also went well! At 8:45 we had our daily briefing with Joe and were given a schedule of the internship. After that, my group and I went down to our office space where we set up shop; I also reviewed some of the material we went over yesterday. At 10am we met up with Dmitry and went over our "homework" from the night before and reviewed information about bell curves, mean, and variance, and learned some new information about reflection coefficients and the Fresnel equation. After that, Dmitry printed out some information for us about polarization that we read through for about an hour and a half. Then we took a lunch break and met up around 1pm. We went to the main lab where we took a look at the enclosed room that will be used for Tristan's research, which isn't fully constructed yet. It's necessary that the room is enclosed and the air is filtered because dust and dirt will create noise that will affect measurements and data. Dmitry then sho

Twenty-seventh Day

On Friday, Peter and I started to look for error and the Signal to Noise Ratio (SNR) in our pictures. We used MATLAB to look at which pictures had the highest SNR and lowest error. We decided that pictures taken with an exposure time of 8500 microseconds and at lower angles had the best SNR. In the afternoon, we worked on our PowerPoint and did a mock presentation in front of Dmitry. We have a lot of things to change in our presentation organization-wise, but nothing too bad. It was beneficial to verbalize our info, and get constructive criticism. One thing we didn't emphasize enough in our original presentation was what Peter and I actually did, including designing the track and the glass holder. In our final presentation, we are going to explain more of what we actually did, so it will be more fun for us to present and more entertaining for the audience.

Fifth Day

Today, during the morning meeting, all of the interns watched a video description of imaging science. After the morning meeting, I caught Peter up on the information I found about birefringence and then showed him how to use the camera. We then started to research how to measure birefringence and then went up to the tech talk on the second floor. The talk was about how imaging science is used in the biomedical engineering field to create new, less invasive technology. Less invasive technology means that doctors need more external viewing ability through technology such as digital models or physical models. I really enjoyed the talk and was able to learn a lot about biomedical engineering. In the afternoon, Peter and I took a quick break and then continued research about the birefringence   of skin cells. We then looked into some reports that Dmitry suggested about polarimetric imaging of cervix cells that used processes that we might be able to apply in our own research. Tomorrow, w
