Title: OPTICAL COHERENCE TOMOGRAPHIC IMAGING DEVICE AND MEASURING METHOD
Abstract:
This optical coherence tomographic imaging device is provided with a light source unit which simultaneously emits low-coherent light in three colors, R, G and B, and generates a full-color optical coherence tomographic image by irradiating an object of measurement with the low-coherent light in the three colors R, G and B, and detecting interference light resulting from reflected light and reference light for each color, R, G and B. In the optical coherence tomographic imaging device, an image generating unit is provided with a correction processing unit which calculates an attenuation related value related to signal attenuation of interference light signal strengths of the three colors R, G and B for a first-depth region, and which, in accordance with the attenuation related value, corrects the signal strength for a second-depth region deeper than the first-depth region to obtain an interference light corrected signal. The image generating unit generates the full-color optical coherence tomographic image using the corrected signals obtained respectively for R, G and B.
