Residual Aberration Controller for Adjustable Aesthetic Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current imaging optical systems struggle to provide both sharp imaging and desired aesthetic effects in a simple and quick manner, often requiring multiple lenses, increased complexity, and higher costs.
Innovation Solution
A residual aberration controller (RAC) is introduced into the optical path of an image-forming light beam to selectively introduce residual aberrations, allowing for adjustable aesthetic effects such as flare, bokeh, and image softening without defocus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple imaging optical systems are used to provide both sharp and softened images, then aesthetic imaging effects can be achieved, but the total number of imaging optical systems increases and cost increases
Solution Approach 1:
The patent applies universality by designing a single imaging optical system that can perform multiple functions: it can produce both sharp images and softened aesthetic images by adjusting the residual aberration controller. This eliminates the need for multiple separate lenses, as one lens system with adjustable aberration control replaces the need for multiple fixed-function lenses, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The patent applies dynamics by making the residual aberration controller adjustable between different configurations. The controller can dynamically change the amount and type of residual aberrations introduced into the optical path, allowing the same imaging optical system to adapt between producing sharp images (minimal aberration) and softened aesthetic images (increased aberration), providing real-time adaptability without physical lens changes
2Adaptability or versatility
If spherical imaging optical systems are specially designed to produce softer images, then aesthetic effects are achieved, but the lens cannot produce sharp images and requires an additional lens and lens swap
Solution Approach 1:
The patent applies dynamics by implementing an adjustable residual aberration controller that can be reconfigured between different operational states. The controller introduces variable amounts of residual aberration into the optical path, allowing the same lens to dynamically switch between producing sharp images (controller in minimal aberration configuration) and softened aesthetic images (controller in high aberration configuration), eliminating the need for physical lens swaps and making the transition instantaneous and reversible
Solution Approach 2:
The patent applies parameter changes by modifying the residual aberration parameters of the imaging optical system through the adjustable controller. By changing the configuration of the residual aberration controller, the optical system's aberration parameters are adjusted, enabling the same physical lens to produce different image characteristics (sharp vs. softened) without any physical modification to the lens itself, thereby maintaining ease of operation while achieving aesthetic effects
3Adaptability or versatility
If combinations of light sources, filters and specially designed imaging optical systems are used to achieve softened images, then aesthetic effects are achieved, but complexity and cost of implementation increase
Solution Approach 1:
The patent applies merging by integrating the residual aberration control function directly into the imaging optical system itself. Rather than using separate components like filters, light sources, and specially designed lenses in combination, the patent combines the aberration control capability within the optical system through an adjustable controller that modifies the wavefront of light passing through the lens, thereby achieving aesthetic effects with a single integrated system rather than multiple separate components
Solution Approach 2:
The patent applies universality by designing the imaging optical system with built-in residual aberration control capability. The adjustable controller serves multiple functions: it can introduce different types and amounts of residual aberration to create various aesthetic effects, and it can also be adjusted to minimal aberration for sharp imaging. This multi-functional design eliminates the need for separate filters, light sources, and specialized lenses, reducing implementation complexity while maintaining aesthetic versatility

Function Achieved in This Case
The RAC enables quick and reversible adjustments to achieve aesthetic imaging effects, reducing the need for multiple lenses and minimizing cost, while maintaining the sharpness of the image.
Implementation Method 1
The aesthetic effective is caused by the RAC selectively introducing residual aberrations into the wavefront of the image-forming light beam

AI summary
A residual aberration controller arranged in the optical path of an image-forming light beam to create an aesthetic effect in an otherwise sharp image by selectively introducing residual aberrations into the wavefront of the image-forming light beam. The residual aberration controller is adjustable between a first configuration that provides either no substantial change or a relatively small aesthetic change to the otherwise sharp image and a second configuration that provides a substantial change to the sharp image to create the aesthetic effect. Aesthetic effects can include, to varying degrees, flare, bokeh, image softening, anamorphic and related effects that are desirable in certain imaging applications but that are difficult to produce in a quick and reversible manner. The residual aberration controller can be combined with almost any type of objective lens to achieve aesthetic imaging effects quickly, affordably and reversibly by a simple adjustment and without defocus.
