A direct view display system (DVDS) and a method to operate it are provided herein. The DVDS may include: a variable optical power element (VOPE); a transparent active image source located with the VOPE on a common optical axis going from an outside scene to an eye position of a viewer; and a time division multiplexer (TDM) configured to control the VOPE and the transparent active image source, wherein the TDM is configured in a certain time period to cause the transparent active image source to be in a transparent state and the VOPE to exhibit no optical power, and wherein the TDM is configured in another time period to cause said transparent active image source to exhibit an image and said VOPE to apply non-zero optical power, for projecting the image onto the eye position at a desirable distance therefrom.

Direct view display with transparent variable optical power elements

Optical systems and methods are provided, which combine see-through view of the real world and display source images using a conical optical combiner cut to have flat surfaces normal to the viewer line of sight. The conical shape minimizes interferences in the view of the real world as the edges of the optical combiner are tangent to the viewer vision field of view and the inner part of the optical combiner is semitransparent. Additionally, the optical system comprises a beam splitter, a shutter(s) for attenuating or blocking the see-through path and may employ polarizing element to improve the contrast between the scene observation and the projected display and thus enabling selective viewing of either. The system may also be configured to enable diopter adjustment and virtual display distance adjustments.

Conical optical combiner

A system and method for providing extended field of view. In one embodiment, the present invention is directed to provide extended field of view for a user of a personal display system. The system may include an image source coupled to relay optics, to redirecting unit and to reflecting unit, and may optionally be mounted in a helmet.

Personal display system with extended field of view

Device for combining a scene image, produced by an imaging system, with an induced image, the imaging system including an eyepiece optics and at least a display screen producing the scene image, the eyepiece optics being located between the display screen and the eye of the observer, the device including an optical director projecting the induced image toward a diffusive surface, the diffusive surface being located between the display screen and the eyepiece optics, wherein the diffusive surface reflects the induced image back, toward the observer, through the eyepiece optics, and wherein the diffusive surface transmits the scene image from the display screen toward the observer, through the eyepiece optics.
