Summary
This study introduces a novel panoramic optical system with two fields of view (FOV) channels integrated into a single panoramic annular lens (PAL). This innovation enhances imaging capabilities without increasing the device
Area of Science:
- Optical Engineering
- Imaging Systems
Background:
- Conventional panoramic annular lenses (PALs) offer a wide field of view (FOV) but are limited to a single imaging channel.
- Expanding FOV capabilities often requires larger or more complex optical systems.
Purpose of the Study:
- To develop a new panoramic optical system that incorporates an additional FOV channel within the existing physical constraints of a conventional PAL.
- To achieve dual-channel imaging without optical path interference and using a single image plane.
Main Methods:
- Design and development of a novel panoramic annular lens (PAL) capable of housing two independent FOV channels.
- Integration of optical paths for front and back imaging within the same PAL.
- Realization of two distinct images on a single image plane.
Main Results:
- A prototype PAL was successfully developed, demonstrating the feasibility of the dual-channel concept.
- The system provides a front FOV channel with coverage of 360° × (38-80°).
- The system provides a back FOV channel with coverage of 360° × (102-140°).
Conclusions:
- The proposed panoramic optical system effectively integrates two FOV channels into a single PAL.
- This design achieves enhanced imaging capabilities without increasing the physical footprint of the optical system.
- The dual-channel PAL offers versatile panoramic imaging solutions for various applications.
