The world needs your light....
Meeting started at 8:55 a.m. at Ngee Ann Polytechnic
Mr Lee started off by explaining to us the shortcomings of our previous design, such as being too compact and yet the outer casing was bulky etc. Mr Lee then introduced to us new concepts which led to newer designs for the laser projector. We then went to Research Lab 1 to determine which material would be most suitable for a image display surface. After numerous experiments involving laser diodes, we concluded that white paper and cement were equally good.
Kenneth was then tasked to read Joseph W. Goodman's Book "Introduction to Fourier Optics" pages 137-160. It contained information about frequency response for diffraction-limited incoherent imaging, optical transfer function, aberrations and their effects on frequency response, comparison of coherent and incoherent imaging.
Kiat Long then searched the catalogue for the laser power supply. Jonathan was observing Mr Lee's work on machinery, offering valuable advice. He was using the milling machine to smoothen a metal block, removing the layer of rust over it. However, the block had to be coated with a layer of silver polish to make it look more appealing to the audience. Also, we all went through the project proposal, Mr Lee pointed out to us the places which required more elaboration, such as the rationale for our project and our methodology.
Meeting ended at 12:45 p.m.
