This disclosure relates to an optical device which includes means for forming a pair of images in an optical channel and means for viewing the images. The viewing means includes a liquid crystal display, an eyelens, and an analyzer arranged between the liquid crystal display and the eyelens. In order to provide for selectively viewing one of the images, the image forming means is adapted to orthogonally polarize the images and project the polarized images onto the liquid crystal display. When the display is energized, one of the images can be viewed through the eyelens; and when the display is unenergized, the other image can be viewed through the eyelens.
