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.

We discussed the display screen and it was pointed out that a screen using mist was not very good because it is extremely bulky and hard to transport around. Furthermore, the cost of the screen is exhorbitant. We are thus consideing an alternative method.
Also, we figured out that 1 of the laser power supply had been damaged, either due to wear-and-tear or a short circuit. As such, the laser power supply would have to be replaced ASAP or the laser cannot function. Next, we also watched the machining portion, Mr Lee kindly demonstrated to us how two different parts are attached together, either by screws or by liquid gels which solidify after a while. We also had to take out the upper cover of our projector prototype so as to remove the damaged power supply.
Lastly, we checked our 3D MAX images stored in the C;/ drive of the main 3D computer of the campus. The images were still intact and in proper sequence.
Meeting ended by 5 p.m.

Meeting started at 9 a.m.
We called up the supplier for the projector plug and instructed them to deliver the plug by today if possible. This is to ensure further developments of our work can proceed on. The two boxes containing the mechanical components can then be attached together.
Next, using 3D MAX software, the three of us worked on our images to be inputted into the CGH. Jonathan drew a rotating mug, Kiat Long drew a rotating car tyre while Kenneth drew a rotating truck. We then rendered our images for each of the 100 frame images, thus producing 100 Bitmap images for each form. These images can then be inputted into the CGH Hologram via a Labview source code when they are ready.
Meeting ended at 1:30 p.m.
