Solution Overview
Problem
Existing digital holography systems struggle to quickly find the in-focus position for objects moving through microchannels, especially when capturing real-time images, leading to unclear reconstructed images due to varying depth positions.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If real-time processing of original images is performed to capture moving objects through microchannels, then the ability to observe dynamic processes is improved, but the time required to search for in-focus position increases, causing unclear reconstructed images
Solution Approach 1:
The system performs preliminary actions by recording in-focus positions from previous imaging cycles and using these recorded positions as initial positions for the next search. This preliminary accumulation of focus position data eliminates the need to start the search from scratch each time, significantly reducing the search time while maintaining real-time processing capability.
Solution Approach 2:
The system implements feedback by using the in-focus position detected in the current imaging cycle as the initial position for the next imaging cycle. This feedback mechanism creates a continuous optimization loop where each iteration builds upon the previous results, enabling rapid convergence to the correct in-focus position without requiring exhaustive search each time.
2Adaptability or versatility
If the reconstruction position is changed to accommodate varying depth positions of moving objects, then the adaptability to different focal planes is improved, but the complexity of processing increases
Solution Approach 1:
The system dynamically adjusts the reconstruction position based on the detected in-focus position from the original image. Instead of using a fixed reconstruction position, the system adapts the reconstruction position to match the actual depth position of the object being observed. This dynamic adjustment is achieved through automated detection and positioning algorithms that respond to the varying depth positions of moving objects through the microchannel.

AI summary
An information processing device that reconstructs an original image including an interference fringe image of an object to be observed includes at least one processor. The processor acquires the original image, generates a reconstructed image while changing a reconstruction position from an initial position based on the original image, calculates sharpness of the reconstructed image each time the reconstructed image is generated and detects an in-focus position where the calculated sharpness is maximized, records the in-focus position, decides the initial position in a next reconstruction processing based on the in-focus position, and repeats the original image acquisition every one imaging cycle.
