An increasing tendency to project information leads to a potential market opportunity to produce a compact and cheap projector to display symbols for industrial applications. A projection optical system is developed for a tilted surface configuration using modern optic software. Projectors need to produce the brightest image possible, but they also need to compensate for the multiple optical aberrations to achieve a good quality image. In this thesis, a design with 2 lenses is able to project an image of 1'8m with a RMS spot radius less than 10mm and a MTF at 50% of 0'367 cycles/mm. Additionally a study of several possible masks technologies is performed, being the best candidate the well stablished photolith for this application. |
