Abstract
An image projection system having an optical projector and a method for projecting an image. The image projection system enables viewing the images in three dimensions and securely viewing the images in a public forum. The image projection system may include a portable, handheld optical projector that is spaced apart from a display screen and that redirects an image signal to the display screen. The image signal is scattered by the display screen and transmitted to a viewer'"'"'s eyes through a set of eyewear worn by the viewer. The display screen preserves the polarization state of the image signal. The portable handheld optical projector may be a cellular phone, a personal digital assistant, a portable computer, or the like that includes one or more sets of light emission systems capable of projecting the image signal. The optical projector may be portable and handheld, or stationary or semi-stationary.
