Abstract
The main challenge in multimode fiber imaging is modal scrambling caused by environmental fluctuation. How to get high contrast and high stable imaging is the main question. In this presentation, we propose some methods to increase the contrast-to-noise ratio and stability of multimode fiber imaging. Wavelength modulation is introduced to suppress the background. Exhaustive bending effect was used to improve the imaging stability. Wavelength modulation is introduced to enhance the CNR four fold in a 200 μm field-of-view imaging. We show a near diffraction limited focusing capability at imaging depths of up to 150 µm with near constant lateral resolutions of 2.1 µm. The imaging of small fluorescent beads embedded in a 3D matrix was demonstrated.
