Method for detection and location of a difference in density and/or structure and/or chemical composition of a biological tissue ( 7 ) which is subjected to continuous illumination in a first determined band of frequencies, causing the former to generate a phenomenon of fluorescence, autofluorescence or luminescence in a second band of frequencies. The method includes the following stages: the biological tissue thus illuminated is visually captured by colour video elements provided with image sensors with a mosaic of pixels provided with additional colour filters; for each image point thus obtained 1) information relating to the energy received by each pixel is collected in order to reconstitute an image of the biological tissue ( 7 ), b) amplification occurs for the signal corresponding to the energy received in the second frequency band in order to characterize the biological tissue ( 7 ) difference or to cause the image thus obtained to appear. |
