The world needs your light....
Meeting started at 2:30 p.m. at Ngee Ann Polytechnic.
We had to test out the transferring of images into the projector's hard drive once again. This is because the transfer cable has just been replaced and we need to ensure it can function optimally. We transferred Jonathan's images of a rotating cup as a sample because the image was the least complicated and had the smallest file size. The image transfer had proceeded rather smoothly until the last 10 images, which could not be transferred because the maximum storage capacity of the projector's hard drive had been reached. The three of us were consideing whether to replace the storage drive of the projector with one of larger file size.
Next, we observed a welding process. Screws are permanently attached to a metal block via the solidified welding liquid. A pointer placed in an immersion heater of 400 degree Celsius was used to pick up welding liquid which was then applied onto the screw. About 2 minutes later, the screw was permanently fixed to that region. Mr Lee then did the same to the other screws on a perspex plate so as to fit the plate in place.
Kiat Long was then given a book on diffraction optics to read. It considered the main theories of diffraction and interferenc, such as Ferauver's theorem. These information were then incorporated into the project proposal and report. Mr Lee also told us how we can improve our proposal by mentioning more about diffraction optics. Not too much emphasis should be placed on the application of lasers because it might cause the readers to lose track of direction.
Meeting ended at 5:30 p.m.
