PROBLEM TO BE SOLVED: To provide a signal processing device, an optical tomographic measuring device, and a signal processing method which effectively eliminate the noises caused by multiple-time reflection.SOLUTION: The signal processing device is a signal processing device for an optical tomographic measuring apparatus which generates measurement light and reference light and measures a tomographic structure of a subject on the basis of the signal intensity of interference light between the reference light and return light of the measurement light from the subject. A calculation unit is configured to calculate, in the return light, the signal intensity of simple reflection which is single-time reflection of the measurement light at each of plural layers virtually set in the depth direction from the surface layer side of the subject. The calculation unit is also configured to calculate, on the basis of the signal intensity of the simple reflection, the signal intensity of multiple-time reflection, or the signal intensity of return light generated by being reflected three times or more at each of the plurality of layers.SELECTED DRAWING: Figure 22 |
