  • Ultra-compact folded-beam path confocal endomicroscope
    Patent number: 12259543
    Abstract: A compact single-axis confocal endomicroscope is provided, capable of complying with 2.8 mm diameter endoscope space requirements. The single-axis confocal endomicroscope uses a folded path design achieved between a fixed mirror and a lateral plane scanning mirror thereby producing high numerical apertures that allow for diffraction-limited resolution in sub-surface scanning. The scanning mirror has a central aperture that allows for illumination beam expansion in the folded path design.
    Type: Grant

  • Ultra-compact microsystems-based single axis confocal endomicroscope
    Publication number: 20220160232
    Abstract: A compact single-axis confocal endomicroscope is provided, capable of complying within 2.8 mm diameter endoscope space requirements. The single-axis confocal endomicroscope uses a folded path design achieved between a fixed mirror and a lateral plane scanning mirror thereby producing a high numerical aperture that allows for diffraction-limited resolution with sub-surface depths. The scanning mirror is formed on a fixed-position, scanning MEMS assembly and has a central aperture that allows for illumination beam expansion in the folded path design. A series of spacers are used to retain beam focusing optical elements in fixed positioned relative to the scanning MEMS assembly for coupling with a single mode fiber.
