Wide field of view hybrid holographic display

1. A system for displaying a wide Field of View (FoV) scene including a three-dimensional image within the scene, comprising:

a head mounted display (HMD) comprising:

a first display for producing a first, three-dimensional (3D) portion of a scene;

an optical system for imaging the first 3D image toward a center of a viewer's field-of-view (FOV);

a second display for producing a different resolution second image of a second portion of the scene next to the first 3D image; and

a viewer pupil tracking component for tracking the viewer's pupil,

wherein the optical system is arranged to allow the viewer a real view of the real world through the optical system, and

the viewer pupil tracking component provides data for controlling the first display and the optical system for displaying the first 3D image to the center of the viewer's FOV,

thereby combining a view of the first 3D image, the second image and the real world.

2. The system of claim 1 , in which the second display comprises a lower spatial resolution display than the first display.

3. The system of claim 1 , in which the second display comprises a display for producing a stereoscopic image.

4. The system of claim 1 , in which the second display comprises an SLM for producing a 3D image.

5. The system of claim 1 , in which the optical system for producing the first 3D image and the second display for producing the second image are configured to display the first 3D image and the second image spanning together a total angle in a range of 60-110 degrees.

6. The system of claim 1 , in which two instances of first displays, two optical systems, and two instances of second displays are configured to display the first 3D image and the second image to the viewer's two eyes spanning an angle in a range of 90-200 degrees.

7. The system of claim 1 in which the optical system is configured to display the first 3D image spanning an angle in a range of 5-35 degrees.

8. The system of claim 1 and further comprising a controllable tilting mirror, and wherein:

imaging the first 3D image toward a center of a viewer's field-of-view (FOV) comprises imaging the first 3D image on the controllable tilting mirror and re-imaging the first 3D image toward the center of the viewer's FOV; and

the second display is located next to the controllable tilting mirror, arranged to display the second image next to the first 3D image.

9. A system for displaying a wide Field of View (FoV) scene including a three-dimensional image within the scene, comprising:

a head mounted display (HMD) comprising:

a first display for producing a first, three-dimensional (3D) portion of a scene;

an optical system for imaging the first 3D image toward a center of a viewer's field-of-view (FOV);

a second display for producing a different resolution second image of a second portion of the scene next to the first 3D image;

wherein:

the first display and the optical system for producing the first 3D image comprises two Spatial Light Modulators (SLMs) and two optical systems, for producing two first 3D images, one for each one of a viewer's two eyes;

the second display for producing the second image next to the first 3D image comprises two image displays for producing at least two second images each one next to each one of the first 3D images, and

the optical system is arranged to allow the viewer a real view of the real world through the optical system,

thereby combining a view of the first 3D image, the second image and the real world.

10. A method for displaying a wide Field of View (FoV) scene including a three-dimensional image within the scene, the method comprising:

setting pixel values in a first display for producing a first three-dimensional (3D) image;

illuminating the first display with light, thereby producing the first 3D image;

setting pixel values in a second display for producing a second image; and

illuminating the second display, thereby producing the second image,

wherein

the first 3D image is displayed at a center of a scene;

the second image is displayed to a viewer's retina, away from a center of the viewer's field-of-view (FOV), as part of the scene and next to the first 3D image; and

the first 3D image provides, for each object in the first 3D image, at least two depth cues:

a correct eye focus accommodation; and

a correct eye convergence.

11. The method of claim 10 and further comprising

allowing a real view of the real world to be viewable through and around the first 3D image and the second image,

wherein

the real view of the real world is also viewable as part of the scene.

12. The method of claim 10 , whereinthe first 3D image is displayed without causing a vergence-accommodation conflict for the viewer.

13. The method of claim 10 , and further comprising:

tracking the viewer's pupil; and

controlling the displaying the first 3D image to direct the first 3D image to the center of the viewer's field-of-view (FOV) using a direction-adjustable optical element.

14. The method of claim 10 , in which the second image comprises a lower spatial resolution display than the first 3D image.

15. The method of claim 10 , in which the second image comprises a stereoscopic image intended for one of the viewer's eyes.

16. The method of claim 10 , in which the second image comprises a 3D image.

17. The method of claim 10 , in which:

the displaying the first 3D image comprises displaying two first 3D images each one to each one of two viewer's eyes; and

the displaying the second image next to the first 3D image comprises displaying two second images, each one next to each one of the first 3D images.
