Post-reflection- QiOptiq

It was a QiOptiq talk by Mr Ronian Siew today. Ms Ivy Wang, a visitor from Life Tech came down and join us in the QiOptiq course. Mr Siew went through with us his journey in life and how he end up choosing optic engineering. He also gave a lesson on lenses, a more unique way compared to normal physics lesson. For example, he came up with an analogy for how a converging lens actually works. He treat light rays as racers and the lens is suppose to make sure that all the racers will end up in the same position on the other side of the lens... So, he used mud to represent the thickness of the lens. As mud would slow down racers, the racers with the shortest would experience most mud in order for all the racers to meet at the same position. It is the same for light, the light rays will slow down more as it passes through the middle of the lens while light rays will slow down less as it enters from the two ends of the lens. Interesting? I feel that this method can make us remember how a lens works, as well as explain why converging lens is able to converge!

We are also suppose to come up with a invention that could successfully see an oral cavity in darkness. Our group, consisting Bram, Nicholas, Jia Qi and me came up with the theory on how our prototype work. We spent a lot of time trying to get the correct orientation and size of the image. We decided to use the flashlight in our phone to shine into the optical fibre that we have and use 2 10x lens placed in front of the camera lens so as to capture the image of a specific part of the oral cavity. There is also 1 group that made a retractable lens that could refocus image as it changes the focal length! How cool is that! 

After this lesson with Mr Siew, I feel that optics could be used everywhere in our daily life and inventions could be made even by us, students! Although it might be a small prototype, I can see great value if our ideas could be adopted and really created into a useful product...
