Abstract: A projector structure, such as a stage use projector, is provided for managing light projection and suitable for replacing a “Gobo” device. The projector structure has a digital micromirror device (DMD) and a refraction and/or reflection device for circulating light beams (R) around the digital micromirror device and maintaining the coaxiality between the light source and the projection lenses.
