Immersive Optical Projection System

Smart overview of the Invention

Introduction: The system integrates a virtual and augmented reality setup with an immersive sound system, sensors, power source, communications, data processing, and an advanced optical system. It offers photoreceptor density resolution, wide-angle views, high contrast, binocular vision, and continuous depth of field images for a fully immersive experience. A key feature is a miniaturized array of projectors arranged to cover retina photoreceptive areas, delivering controllable beams of light directly into the eye.

Optical System: The optical system includes segmented projector arrays that enhance dynamic performance. An adaptive optics reflector with independently controllable elements alters beam properties to create the perception of virtual objects at varying distances. A two-dimensional array of micro projectors provides direct projection into the eye for a fully immersive visual experience.

Background and Field: The system relates to virtual reality technologies that deliver synthetic content directly to the eye and augmented reality systems that blend generated content with real-world views. It addresses the need for an immersive device that stimulates each of the retina's photoreceptors to simulate depth perception, binocular parallax, and a broad color space without compromising vestibular function.

Current Art Limitations: Existing technologies like movie projectors and 3D glasses offer limited immersion due to their inability to produce divergent ray fields and true depth perception. Virtual reality goggles attempt to provide total immersion but face challenges in synchronizing head motions with visual fields and often lead to sensory conflicts causing motion sickness.

Technical Details: The system utilizes a micromachined beam steering device capable of precise beam direction with two degrees of freedom. This is achieved through electrostatic forces applied to gimbaled micromirror assemblies. The design allows for accurate alignment and control of optical elements, enhancing the immersive experience by precisely directing light beams into the viewer's eyes.
