Figure 7From: Using an oblique incident laser beam to measure the optical properties of stomach mucosa/submucosa tissue The shift Δx of diffuse reflectance of normal stomach mucosa/submucosa tissues in the cardiac orifice at 635, 730, 808, 890 and 980 nm. The blank dots correspond to the average shift Δx of diffuse reflectance and the vertical lines show the SD values.Back to article page
