Since this project is based on an FTIR setup, the sides of the acrylic sheet need to polished as to allow TIR. However since most factory cut acrylic sheets are cut using a saw the they are really rough…
The Osyris Digital IO prototype consists of an acrylic sheet which will be mounted in a frame. Having tried to maintain a (4:3) aspect ratio. The The Acrylic Sheet is 24″ x 32″ = 60cm x 80cm of size and 3/8″ = 0.921cm thick. However the actual projection area is 58cm x 78 cm.
The acrylic sheet was purchased from Laird Plastics Toronto (Mississauga) for $55 CAD, it came in a traditional paper protective layer.
Below is the process of how to i polished my acrylic sheet.
