Figure 1From: The impact of laser ablation on optical soft tissue differentiation for tissue specific laser surgery-an experimental ex vivo studyExperimental set-up for optical measurements: 1) Diffuse Reflectance Spectroscopy before laser ablation, 2) Tissue ablation with an Er:YAG laser (spot size ø 4 mm), 3) Diffuse Reflectance Spectroscopy in the area of ablation (a. Spectrometer, b. Pulsed xenon lamp, c. Reflection/backscattering probe, d. Tissue sample (pig, ex vivo), e. Er:YAG laser).Back to article page
