LASER Beam was applied to various organs of canine and biophysical changes were photographed by a high speed camera, 4,000 frames per second. Laser Beam was set constant 17, 5 Joules (=35 watts with 0.5 seconds duration) to irradiate organs. Very instantaneous phenomenon were photographed and recorded by ultra high speed camera, John Hadland Mfg Co., make 16 mm Camera and films were analyzed frame to measure filmlength of each biophysical change. Organs applied were, Vocal cord, Tongue, Skin, Cartilage and Bone. These are categorized into mucous membrane group, dry tissue group and group in between. Time length between certain points was precisely calculated by a motion analyzer. A): Onset of irradiation to tissue B): Onset of vacuole C): Peak of vacuolization & erupt ion & eruption (=evaporation) D):Onset of vacuoles E): Onset of carbonization F): Completion F): Completion of carbonization at bottom of crater G): End of carbonization
Vacuolization was observed clearly in mucous membrane of tongue and vocal cord, and fashion of vaporization and eruption were found to be same in each mucous membrane. On the other hand, very little vaporization and eruption were observed over the periostium of bone and perichondrium of cartilage. Instead, rapid detuochment of periostium and perichondrium were observed. Skin showed react ion of the these in between ultra high speed camera enabled to prove the difference of instantaneous reaction of tissues among the various organs.
