Abstract
Systems and methods for diagnosing epithelial neoplasia and other conditions includes, in a representative embodiment, providing the human eyes with a filter to observe the autofluorescence of a tissue sample. Using optimized wavelengths from a filtered light source, a sample is illuminated. The radiation from the sample is filtered to enhance the contrast between a normal sample and a diseased sample observable by the human eye.
