Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional adaptive optics systems face challenges in accurately correcting wavefront phase aberration, especially when the observation target and fluctuation layer are close or the target is minute, leading to unstable correction control and a narrow effective correction range.
Innovation Solution
An adaptive optics system with a wavefront phase modulator and an imaging-conjugated position adjustment mechanism that adjusts the position of the fluctuation correction surface relative to the fluctuation layer, using relay lenses and turn-back optical systems to change optical distances and align the imaging-conjugated surfaces, allowing for precise wavefront phase correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional adaptive optics systems are used, then wavefront phase aberration correction is provided, but correction accuracy deteriorates when the observation target and fluctuation layer are close or the target is minute
Solution Approach 1:
The patent introduces an imaging-conjugated position adjustment mechanism that dynamically adjusts the position of the fluctuation correction surface within the specimen. This dynamic adjustment capability allows the system to adapt to different observation scenarios (close targets, minute targets, varying depths) by repositioning the correction surface to maintain optimal imaging-conjugation, thereby resolving the contradiction between maintaining high correction accuracy and expanding the effective correction range across diverse observation conditions.
Solution Approach 2:
The patent segments the correction function by introducing a movable fluctuation correction surface that can be independently positioned at different depths within the specimen. This segmentation allows different regions of the specimen to be corrected optimally by adjusting the correction surface position, enabling high-accuracy correction for both close and distant targets, as well as minute and extended structures, without compromising the other.
2Device complexity
If special optical systems using aspheric lenses or light-driven modulators are used to reduce device size, then device complexity is reduced, but simplicity and flexibility are lost
Solution Approach 1:
The patent employs a universal adjustment mechanism that can accommodate various wavefront corrector types (deformable mirrors, spatial light modulators) and optical configurations. The imaging-conjugated position adjustment mechanism serves multiple functions: it adjusts the correction surface position, maintains imaging-conjugation relationships, and adapts to different specimen configurations. This multi-functionality allows the system to maintain simplicity and flexibility while controlling device size, without requiring specialized aspheric lenses or light-driven modulators.
3Device complexity
If the fluctuation correction surface position is fixed, then device configuration is simplified, but correction stability deteriorates for varying observation conditions
Solution Approach 1:
The patent implements a feedback control mechanism where the imaging-conjugated position adjustment mechanism continuously monitors and adjusts the fluctuation correction surface position to maintain optimal imaging-conjugation with the fluctuation layer. This feedback ensures that regardless of changes in observation conditions (target distance, size, depth), the correction surface remains properly positioned, thereby maintaining correction control stability without significantly complicating the device configuration.

AI summary
The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.
