Summary
This study introduces adaptive liquid (AL) lenses into double-sided telecentric zoom systems, significantly reducing mechanical components. The developed design method provides a viable initial structure for these advanced optical systems.
Area of Science:
- Optical Engineering
- Machine Vision Systems
Background:
- Traditional zoom systems often involve complex mechanical structures.
- Adaptive liquid (AL) lenses offer a potential solution for miniaturization and simplified mechanical design.
Purpose of the Study:
- To introduce adaptive liquid (AL) lenses into double-sided telecentric zoom systems.
- To develop a method for designing initial structures for AL lens-based zoom systems.
- To optimize the system for high-precision machine vision applications.
Main Methods:
- Derivation of Gaussian brackets specific to the AL lens system.
- Development of a screening method for initial structure parameter selection.
- Lens module design and subsequent optimization using CODEV software.
Main Results:
- A significant reduction in mechanical motion groups was achieved.
- Telecentricity on both sides was maintained within 0.1°.
- Distortion was controlled below 0.5%, with Modulation Transfer Function (MTF) above 0.3 across all zoom configurations.
Conclusions:
- The proposed design method effectively addresses the challenge of establishing initial structures for AL lens zoom systems.
- The optimized optical system demonstrates high performance suitable for precision machine vision.
- This approach offers a valuable alternative to traditional zoom systems, enabling more compact and efficient designs.
