Multispectral Light Source For Endoscopic Procedures

This paper presents the implementation of an endoscopic system with an opto-mechanical revolver for the interchange of five illumination sources for the in vivo diagnostic of abnormalities in liver tissue. Also, the system allows to save images produced by light reflection or autofluorescence. A pedal was implemented to automatically interchange the illumination sources during the endoscopic procedure. Software was developed to save the images captured by the endocamera. Fatty liver images were taken in an animal model which shows the advance of the disease.
