Abstract
Dual wavelength observation: Projection of light with two central wavelengths, 415 nm and 540 nm, enables us to visualize the mucosal microvascular architecture and mucosal microsurface structure with higher contrast than that is possible with white-light imaging. Bandwidth narrowing: By narrowing the bandwidth of the projected light (bandwidth narrowing), we improve the contrast when examining the microvasculature.
