BI-CYLINDRICAL PIEZOELECTRIC ACTUATED OPTICAL LENS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240094445 titled 'BI-CYLINDRICAL PIEZOELECTRIC ACTUATED OPTICAL LENS

Simplified Explanation

The patent application describes a liquid lens with flexible transparent active layers on both sides of a fluid that can be deformed along two distinct axes using piezoelectric materials.

• The flexible transparent active layers deform the lens cylindrically along different axes to achieve a net spherical deformation or a combination of spherical and cylindrical deformation with minimal distortion.
• The active layers can be made of polymer or ceramic materials with isotropic or anisotropic mechanical stiffness.
• The active layers are arranged to actuate the lens in response to applied voltage, allowing for precise control over the deformation of the lens.

Potential Applications

This technology could be used in adjustable focus lenses for cameras, microscopes, or other optical devices.

Problems Solved

This technology solves the problem of achieving precise and controlled deformation of a liquid lens for optical applications.

Benefits

The benefits of this technology include improved image quality, faster autofocus capabilities, and increased flexibility in optical design.

Potential Commercial Applications

A potential commercial application of this technology could be in the manufacturing of high-quality camera lenses for smartphones or professional cameras.

Possible Prior Art

One possible prior art for this technology could be the use of piezoelectric materials in deformable lenses, but the specific arrangement of dual transparent active layers for controlled deformation may be novel.

How does this technology compare to existing liquid lens technologies on the market?

This technology offers more precise control over the deformation of the lens compared to traditional liquid lens designs, potentially leading to improved optical performance.

What are the potential challenges in scaling up this technology for mass production?

One potential challenge in scaling up this technology could be ensuring consistent performance and quality control across a large number of lenses produced.

Original Abstract Submitted

a liquid lens with flexible transparent active layers on both sides of a fluid is transformed along two distinct deformation axes. the flexible transparent active layers include piezoelectric materials that actuate the lens in response to applied voltage(s). the piezoelectric properties and actuation mechanism of the transparent layers are arranged to deform the lens cylindrically along different axes resulting in a net spherical deformation or a combination of spherical and cylindrical deformation with substantially less distortion than spherically deforming layers. the piezoelectric active layers may be polymer or ceramic with isotropic or anisotropic mechanical stiffness. alternatively, a pair of transparent, internal layers are positioned between the front and rear surfaces. the active layers, front and/or rear, are dual layers affixed together with an adhesive or single layers.
