The present invention provides an optical system comprises a scanning spectrometer incorporating an electronic light modulator and digital signal processing means. The spectrometer technique combined with optical signal encoding provides the ability to obtain spectral signatures and identify optical patterns of biological tissue. One example of biological tissue scanning includes techniques such as identification of optical patterns of normal and abnormal tissues in addition to the delineation of these spectral patterns between the abnormal and normal tissue. Due to an enhanced signal-to- noise ratio provided by the optical system according to the present invention, this optical system can detect patterns in biological tissue that may be more subtle than those patterns that would be possible to obtain with currently available optical systems.
L'invention concerne un système optique comprenant un spectromètre à balayage doté d'un modulateur de lumière électronique et d'un dispositif de traitement de signaux numériques. La technique de spectrométrie combinée au codage de signaux optiques permet d'obtenir des signatures spectrales et d'identifier des modèles optiques de tissus biologiques. Un exemple de balayage de tissu biologique comprend des techniques telles que l'identification de modèles optiques de tissus normaux et anormaux, outre la délimitation de ces modèles spectraux entre le tissu normal et le tissu anormal. Présentant un rapport signal/bruit amélioré, le système optique de la présente invention peut détecter dans un tissu biologique des modèles plus subtils que les modèles pouvant être obtenus au moyen de systèmes optiques courants.
