Patent

CA 2578183

The disclosure generally relates to a method and apparatus for a fiberscope. In one embodiment, the disclosure relates to a chemical imaging fiberscope for imaging and collecting optical spectra from a sample having at least one illumination fiber (14) for transmitting light from a first an a second light source to a distal end of a fiberscope; a dichroic mirror (30) disposed at said distal end of the fiberscope such that the light from said first light source passes substantially straight through said mirror and light of a predetermined wavelength from said second light source is substantially reflected by said mirror toward said sample to thereby illuminate said sample; and at least one collection fiber (38) for receiving light from said illuminated sample and transmitting the received light to an optical device.

Cette invention concerne, de façon générale, un procédé et un appareil pour un fibroscope. Dans un mode de réalisation, cette invention concerne un fibroscope d'imagerie chimique servant à représenter en images et à recueillir les spectres optiques d'un échantillon, ce fibroscope comprenant à cet effet au moins une fibre éclairante destinée à transmettre le rayonnement lumineux d'une première et d'une seconde source lumineuse vers une extrémité distale du fibroscope; un miroir dichroïque disposé au niveau de l'extrémité distale du fibroscope pour que le rayonnement lumineux provenant de la première source lumineuse traverse essentiellement en ligne droite le miroir, le rayonnement lumineux d'une longueur d'onde prédéterminée provenant de la seconde source lumineuse soit essentiellement réfléchie par ledit miroir en direction de l'échantillon, afin d'éclairer ce dernier; et au moins une fibre collectrice destinée à recevoir le rayonnement lumineux provenant de l'échantillon éclairé et à transmettre le rayonnement lumineux ainsi reçu vers un dispositif optique.
