Improved spot formation for flexible multi-mode fiber endoscope using partial reflector
Ruo Yu Gu, Elaine Chou, Cory Rewcastle +2
Multi-mode fiber (MMF) endoscopes are a new type of endoscope that use only a single optical fiber to transmit images, achieving much higher spatial resolution for a given diameter…
