Information optics approach in diagnostics of malignant changes of biological tissues

The information optics techniques, such as polarimetry and spectropolarimetry, are applied for identifying the changes of optical-geometrical structure in various biological tissues with solid tumours. It is shown that a linear dichroism appears in biological tissues (human esophagus, muscle tissue of rats, human prostate tissue, and cervical smear) with cancer diseases whose magnitude depends on the type of tissue and on the time of cancer process development.
