Depth Perception and Spatial Vision

Depth Perception and Spatial Vision

Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

Optics and Photonics
Display Technology
Holography

Background:

Traditional holographic displays face limitations in viewing angle and resolution.
Existing technologies often require bulky components or complex setups.

Purpose of the Study:

To propose and demonstrate a binocular holographic floating display with an expanded viewing angle.
To achieve high-resolution, full-color holographic imagery for immersive applications.

Main Methods:

The proposed device utilizes two phase-modulation spatial light modulators (SLMs).
A dihedral corner reflector array (DCRA) is employed to generate system exit pupils.
Exit pupils are positioned at the observer's eye locus to overcome SLM dimension constraints.

Main Results:

The system achieves an image resolution of 3 arc minutes with a laser light source at distances under 20 cm.
The display design overcomes the viewing angle limitation imposed by SLM dimensions.
Full-color display capabilities are successfully demonstrated.

Conclusions:

The proposed binocular holographic floating display offers a promising solution for wide-angle, high-resolution holographic imagery.
This technology has potential applications in augmented reality, virtual reality, and advanced visualization systems.
