This morning Lauren gave Henry and me a really intriguing challenge: to make a real camera by using CCD. CCD camera is only able to gather the intensity of the light, functioning similarly to a sensor in the real image capturing camera. The whole morning we were basically trying to figure out how the objective worked and camera imaging worked. After that, I used Focus Equation again and used inverse propagation formula to predict the position of the CCD. Later Lauren told me that what she wanted me to do was actually to make the camera work for natural light first. So classic "1 / d0 + 1 / di = 1 / f " equation appeared again and Henry and I started solving system equations. I was solving it manually which made things way more complicated comparing to what Henry did by solving in Matlab.
Finally, we actually tested our calculations by constructing a small experiment. We changed the distance between light source and a convex lens, and compared the result with the answers we got by using calculations. We found that short distances worked pretty well, but long distances didn't. We would continue working on it tomorrow.
Some images were taken during the experiment (with Henry):
