Abstract

A method is proposed for mapping laser light distributions in gel phantoms by measurement of the distribution of a fluorescent compound that has been photolabeled to the gel by the laser irradiance. A preliminary study of photolabeling by an argon laser using tetrabrominated rhodamine (TBR) was conducted in collagen gel phantoms to illustrate the feasibility of the method. A discussion of the basic quantitative relationships for analysis of measurements is presented.
