The world needs your light....
Meeting started at 0900h at Centre of Innovation
Today, we did a test run of the newly designed projector. After reconnecting the power supply and the laser software, the projector could function properly. However, the image of the rotating head was rather blurred since we were not using a high quality laser and the distance between the laser and screen is large, so there is large energy loss. Also, the ceramic tile, is the screen is rather thick, thus there is a large distance for diffraction of light rays to take place.
Next, we increased the image distance, so as to magnify the image. This was done by moving the laser frame upwards by approximately 8 cm. However, we decided to change to a newer table so as not to compromise with the quality of our image. Also, we are removing one of the leg barriers of the optical table so as to open up a space to insert a smaller table carrying the screen.
To improve the quality of the image, we decided to rectify the source, such as to make one frame per degree; as such, we created 360 images for one complete 360 degrees rotation. These images will then be inputted into the Compact Vision System. With a quantization of images, there would be smoother transition of the displayed image and would thus be of a higher quality. After which, we modified the Labview source cdes further, creating one which could process and transfer the 360 head rotation images.
Meeting ended at 1230h
