Title (EN) FIBER OPTIC PROBE FOR QUANTIFICATION OF COLORIMETRIC REACTIONS
(FR) SONDE A FIBRE OPTIQUE POUR LA QUANTIFICATION DE REACTIONS COLORIMETRIQUES
Abstract:
(EN) A fiber optical probe (12) for colorimetric measurement of chemical properties suitable for the insertion into living tissue. A chemical to be colorimetrically measured is introduced into a sample chamber (22) on the side of the probe (12) near the probe tip (20). A colorimetric substance contained in the sample chamber (22) changes colors in response to chemical properties of the chemical to be colorimetrically measured, thereby changing the amount of light transmitted through the sample chamber (22) by the optical fibers (10, 12).
(FR) Une sonde à fibre optique (12) pour la mesure colorimétrique de propriétés chimiques est destinée à être introduite dans des tissus vivants. Une substance chimique que l'on désire mesurer par colorimétrie est introduite dans une chambre à échantillons (22) côté sonde (12) à proximité de la pointe (20) de la sonde. Une substance colorimétrique contenue dans la chambre à échantillons (22) change de couleur en réponse aux propriétés chimiques de la substance chimique que l'on désire mesurer par colorimétrie, changeant ainsi la quantité de lumière transmise au travers de la chambre à échantillons (22) par des fibres optiques (10, 12).
