VISIVLE IMAGING TECHNIQUE FOR NEAR INFLARED LASER DISTRIBUTION ON AND IN TISSUE

To know the laser light distribution on and in tissues exposed to the lasers is crucial in the therapeutic application of laser technology, but there are few useful techniques to survey such a laser distribution, particularly in the case of low power diode lasers. In our practice of laser therapy the authors have found that near infra-red laser distribution can be easily detected by TVcameras provided CCD image sensor.This experiment has been planned to evaluate the capability of CCD TVcamera to survey the laser light distribution on and in tissues and successfully performed. As a result even in such low power lasers as diode laser of mW order in out put the laser distribution can easily be detected on the TVimage. This technique must be extremely expected to clinical application of lasers.
