Binocular adaptive optics vision analyzer with full control over the complex pupil functions.

Area of Science:

• Ophthalmology
• Vision Science
• Optical Engineering

Background:

• Accurate control of visual stimuli is crucial for understanding binocular vision.
• Existing systems may lack the flexibility to simultaneously adjust amplitude and phase for both eyes.

Purpose of the Study:

• To present a novel, versatile binocular adaptive optics vision analyzer.
• To demonstrate its capability in controlling complex pupil functions for both eyes.
• To showcase its utility in ophthalmic research and visual simulation.

Main Methods:

• Utilized a single reflective liquid crystal on silicon (LCoS) spatial light modulator for simultaneous phase modulation of both pupils.
• Employed a transmissive LCoS spatial light modulator for intensity modulation and pupil masking in each eye.
• Enabled subjects to perform visual tasks through user-defined complex pupil functions for binocular vision.

Main Results:

• Successfully controlled both amplitude and phase of complex pupil functions for each eye.
• Demonstrated system efficiency by recording retinal images of projected stimuli.
• Confirmed the instrument's capability for versatile ophthalmic element design and visual outcome simulation.

Conclusions:

• The developed binocular adaptive optics vision analyzer offers a simple yet powerful platform for binocular vision research.
• Its ability to precisely control visual input makes it invaluable for testing ophthalmic devices and simulating visual perception.
