Using a Stokes digital imaging system, we measured the Stokes vector images of tissue samples from sections of rat livers. The derived Mueller matrix elements can quantitatively provide five-signature spectral imaging data of the bio-samples. The imaging of four independent optical properties: anisotropy, scattering, depolarization and retardation phase of the test sample are derived and reported. Our experimental results are consistent with the general trend predicted by the theoretical model. This polarimetric multi-signature optical technology is a new option of bio-sensing technology to inspect the structures of tissue samples and is potentially useful for critical disease discrimination and medical diagnostics applications.
