An NIR autofluorescence imaging system combined with polarization technique was explored for cancer diagnosis and detection. The AF and FPI images of colonic tissues were acquired. The results show that normal tissue has significantly higher NIR autofluorescence intensity than tumor tissue. The perpendicular-polarized image yields the highest diagnostic accuracy (93%).
