Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for correcting optical aberrations in three-dimensional images require a large number of calculation times, making them time-consuming.
Innovation Solution
An optical aberration correction program that calculates a three-dimensional correction image by obtaining provisional optical transfer functions, generating phase-modulated images, and determining an optimal optical transfer function to deconvolve the original image, reducing aberrations in a shorter time.

Engineering Contradiction Analysis
1Measurement precision
If parametric blind deconvolution method is used to correct optical aberration, then the luminance distribution and PSF can be alternately estimated, but the calculation time becomes excessively long
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing multiple optical transfer functions corresponding to different aberration amounts before actual image correction is needed. When correction is required, the system directly selects and applies the pre-computed transfer function matching the measured aberration, eliminating the need for time-consuming iterative deconvolution calculations while maintaining correction accuracy
Solution Approach 2:
The patent segments the continuous aberration correction problem into discrete levels by dividing the aberration range into multiple segments, each with a corresponding pre-calculated optical transfer function. This segmentation allows the system to handle different aberration magnitudes efficiently by selecting the appropriate segment's transfer function rather than performing full iterative optimization for each case
