AI Technical Summary

Problems solved by technology

While some technologies individually succeed in achieving these desired functions, to date, most technologies have not been able to combine all of these desired functions
This results in an incomplete or even uncomfortable experience for the user
Issues can include low levels of realism and eye strain (due to low resolution or due to poor optical imaging quality), inability to create an immersive environment (small field of view), or excessive strain on the user's head (too heavy)

Embodiment Construction

[0110]Embodiments of the invention include an optical device (each eye) that sends light from one or more digital displays to the region of the pupil range of the eye through one or more optical lenslets, at least one of which is an RXIR lenslet, RXIR lenslets are defined in the sense that a ray of interest (as it travels from a digital display to the eye) undergoes at least four deflections in the following order: refraction (R), reflection (X), total internal or metallic reflection (I ) and refraction (R), where the first refraction (R) and total internal or metallic reflection (I) are performed by the same surface with non-coinciding overlapping clear apertures. (We refer herein to a "surface" as a surface with first-order continuity (ie, the continuity of the slope) or higher). These embodiments use several free-form optical surfaces, meaning that they are surfaces that do not have classical rotational or linear symmetry. Their design is done according to the detailed des...

Abstract

A display device has a display to generate a real image. An optical system has lenslets, each generating a virtual sub-image from a respective partial real image on the display, by each lenslet projecting light from the display to an eye position. The sub-images combine to form a virtual image viewable from the eye position. At least one of the lenslets is an "RXIR" lenslet, in which the light rays from the display to the eye position are deflected sequentially at least four times by a refraction (R), a reflection (X), a total internal or metallic reflection (I), and a refraction (R) in that order.
