Spectrally encoded endoscopy (SEE) now offers real-time subsurface imaging through turbid media. This advanced endoscopic technique enhances visibility for improved diagnostics and surgical applications.

Area of Science:

  • Biomedical optics
  • Medical imaging
  • Endoscopy

Background:

  • Endoscopic imaging offers improved diagnostic capabilities and visibility in surgical settings.
  • Spectrally encoded endoscopy (SEE) is a high-speed imaging technique using a single optical fiber and miniature optics.
  • SEE provides 3D topological imaging capabilities through small-diameter, flexible endoscopic probes.

Purpose of the Study:

  • To configure SEE for subsurface imaging beyond tissue surfaces.
  • To enhance SEE's sensitivity for deeper penetration and complex spectral density acquisition.
  • To demonstrate SEE's capability for real-time subsurface imaging in biological samples.

Main Methods:

  • Configured SEE system with enhanced sensitivity.
  • Acquired complex spectral density for spectrally resolved points.
