Circularly polarized light impinging on a scattering medium undergoes scattering with fine particles and depolarization, which depends on the particle size. Enlarged cell nuclei in cancer tissues can be detected by circularly polarized light scattering non-invasively without staining. The near-infrared circularly polarized light can pick up structural information from a depth of several millimeters, allowing for visualization of cancerous layers creeping under a healthy layer. In this study, we have computationally investigated the model with continuous changes in the depths of cancerous tissue to reconstruct the internal structure of cancerous tissue, suggesting that this method has potential for application in novel medical imaging technology.
