Abstract

We analyze the potential of an optical fiber based remote thermography system. Achievable accuracy, resolution, range, and response time are examined. Experimental results concerning each of these parameters will be presented and compared with theoretical predictions. Results obtained utilizing both silica and fluoride fibers are compared and the benefits and limitations of each are discussed. Two main application areas of this measurement technique are addressed. The use of this technique in the invitro and invivo study of laser induced temperature rise in biological tissue will lead to a better understanding of laser-tissue interaction. Tissue temperature information can be used as a feedback element in a medical laser energy delivery system. Simultaneous laser energy delivery and thernographic sensing through a single fiber will provide "automatic dosing" in many laser coagulative treatments.
