Depth estimation of cancer invasion using scattering of circularly polarized light is studied with refined point-polarization measurements and the polarization probe S3 imaging methods. The degree of polarization (DOCP) values of light scattered from bi-layered biological tissues show clear differences at approximately 1.5 mm in thickness of cancerous layer in both measurement methods. These results indicate that the feasibility of quantitative estimation of cancer progression in early gastric cancer.
