Abstract
A projector including a display screen and an imaging system is provided. The imaging system is adapted for providing an optical image and the optical image is transmitted to the display screen through an optical transmission medium. The refractive index of the optical transmission medium is not equal to one. The transmission path of the optical image is changed by controlling the refraction index of the optical transmission medium in order to thin the projector.
