Signal processing methods, information processing devices, optical coherence tomography devices, and computer software products

Abstract

A technique is provided for obtaining the shape of an interface with strong diffusion. This signal processing method is executed by an information processing apparatus having a control unit. The control unit receives an optical coherence tomography (OCT) signal obtained by optical coherence tomography. Within the OCT signal, it determines a target signal region corresponding only to the second interface, specifically between a first layer group containing one or more layers and a second layer group containing one or more layers, and between the second layer group and a third layer group containing one or more layers. Information related to the shape of the second interface obtained based on the target signal region is then output.
