Abstract
An optical system includes a transparent display, which has a first side configured to be positioned in proximity to an eye of an observer and a second side opposite the first side, and which is configured to project an image into the eye. An image generator is configured to generate a sequence of images during respective display intervals, which are interleaved with blanking intervals, and to transmit the images to the transparent display for projection into the eye. A shutter is positioned on the second side of the display and having a first state in which the shutter blocks optical radiation and a second state in which the shutter transmits optical radiation. A controller drives the image generator and the shutter so that the shutter operates in the first state during the display intervals and in the second state during the blanking intervals.
