Microscope Lens Adjustment Image Position Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing microscope systems face challenges in maintaining image position stability during correction adjustments, leading to lateral offsets and image quality deterioration, which complicates comparisons with reference data.
Innovation Solution
Incorporating a processor that compares the position of images recorded after correction adjustments to reference data, detects position changes, and activates a scanning unit to compensate for these changes, thereby maintaining image position stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the lens unit is adjusted along the optical axis to correct imaging errors, then imaging quality is improved, but lateral offset and image position change occur
Solution Approach 1:
The system uses a feedback mechanism where the processor detects image position changes after correction adjustment by comparing with reference data, then activates the scanning unit to compensate for the lateral offset, creating a closed-loop control system that maintains image position stability
Solution Approach 2:
The system changes the scanning parameters dynamically to compensate for the lateral offset caused by lens unit adjustment. By adjusting the scanning unit's deflection angles or positions, the system counteracts the image position change while preserving the imaging quality improvement
2Manufacturing precision
If the gap between the frame of the lens unit and the guide sleeve is reduced to improve fitting accuracy, then positioning precision is improved, but displaceability is worsened
Solution Approach 1:
The scanning unit acts as an intermediary that compensates for the lateral offset caused by the necessary gap between the lens unit frame and guide sleeve. Instead of trying to eliminate the gap, the system uses the scanning unit to correct the resulting image position change
3Stability of the object's composition
If lateral offset and image position change are compensated for, then image position stability is improved, but device complexity is worsened
Solution Approach 1:
The scanning unit performs its primary function of deflecting the light beam for image recording while also serving the additional function of compensating for lateral offset. This multi-functionality avoids adding a separate compensation mechanism, thereby limiting the increase in device complexity

AI summary
A microscope is provided. The microscope includes a lens system comprising a lens unit, which is adjustable along an optical axis of the lens system to correct an imaging error. The microscope further includes a motor-actuatable adjustment device, which is configured to adjust the lens unit along the optical axis. The microscope also includes a processor and a scanning unit, which is configured to deflect a light beam used for the image recording. The processor is configured to compare a position of an image which has been recorded after a correction adjustment of the lens unit to reference data, detect a change of the position of the image due to the correction adjustment of the lens unit based on the comparison, and activate the scanning unit in such a way that the change of the position of the image is at least partially compensated for.
