Flexible retinal image formation by holographic Maxwellian-view display

Area of Science:

• Optics and Photonics
• Biomedical Engineering
• Ophthalmology

Background:

• Maxwellian-view displays offer potential for low vision aids by bypassing eye refractive errors.
• Conventional displays struggle to provide clear images for individuals with significant visual impairments.

Purpose of the Study:

• To present a novel holographic Maxwellian-view display system.
• To demonstrate electrical control of optical parameters for image formation on the retina.
• To enable correction of eye aberrations for improved visual acuity.

Main Methods:

• Holographic wavefront generation to create a beam converging on the eye's pupil.
• Electrical control of the beam's convergence point and width to adjust focus and depth of field.
• Development and experimental testing of a compact optical system prototype.

Main Results:

• The holographic display successfully formed retinal images independent of eye refractive power.
• Electrical adjustments allowed for dynamic control of the depth of field.
• Correction of eye aberrations, including astigmatism, was achieved through phase modulation.

Conclusions:

• The holographic Maxwellian-view display is a viable technology for low vision assistance.
• This system offers adaptive optical correction and precise image focusing on the retina.
• The proposed compact design and electrical control pave the way for practical low vision devices.
