Abstract

In this work we present an alternative to a full dome digital projection system. The system presented is based upon a single projector coupled to the optical lens (fisheye and objective lens) to scatter the light onto the dome surface. This alternative projection system offers many advantages as manufacturing lower cost and high quality of the image projection. From the practical applications, the system is ideal for use in planetariums lessons.
