The comparison of properties between the endoscopic wide-field imaging and endomicroscopy

	Wide-field imaging	Endomicroscopy
Resolution	Around 100 μm	0.5–20 μm
Field of view	80–140°	Ø0.3–Ø3 mm
Detection target	Macroscopical objects in tissue	Tissue structures in cellular and subcellular scale
Corresponding techniques	Traditional white-light imaging Narrow-band imaging Linked color imaging i-scan	Endocyto Confocal laser endomicroscopy Photoacoustic endoscopy Optical coherent tomography Coherent anti-Stokes Raman scattering Multi-photon endomicroscopy
