Summary
We present a new method for one-dimensional coherent imaging through optical fibers. This technique preserves both amplitude and phase, enabling richer data encoding compared to existing methods.
Area of Science:
- Optics and Photonics
- Coherent Imaging
- Fiber Optics
Background:
- Traditional optical imaging through fibers often loses crucial amplitude and phase information.
- Existing wavelength-division-multiplexed techniques have limitations in encoding comprehensive optical data.
Purpose of the Study:
- To introduce and demonstrate a novel technique for one-dimensional coherent imaging through single-mode optical fibers.
- To preserve both amplitude and phase information of optical signals transmitted via fiber.
- To enable encoding of longitudinal and transverse optical information.
Main Methods:
- Utilized a pulse shaper and a pulse imager for the novel imaging technique.
- Experimental demonstration of the proposed one-dimensional coherent imaging method.
- Analysis of the impact of fiber-material dispersion on the imaging technique.
Main Results:
- Successfully demonstrated one-dimensional coherent imaging through a single-mode optical fiber.
- Preserved both amplitude and phase information, unlike wavelength-division-multiplexed methods.
- Enabled encoding of both longitudinal and transverse optical information.
Conclusions:
- The developed technique offers enhanced capabilities for optical signal encoding and imaging through fibers.
- Fiber-material dispersion effects were analyzed, and potential mitigation strategies were discussed.
- This method advances coherent imaging applications in optical fiber systems.
