Laser Eye Safety Research at APL

چکیده
he focus of this article is a multidisciplinary research program that addresses corneal injury from exposure to infrared laser radiation. Our general methodology combines experimental physical and biological measurements with theoretical analyses to understand corneal damage. Damage thresholds are determined under carefully controlled exposure conditions, and mathematical damage models are developed to correlate and predict damage conditions for other exposure conditions. The information gained supports the evaluation of current permissible exposure limits promulgated by the American National Standards Institute Z136 Laser Safety Standards.

متن کاملOptical Monitoring of the Generation of Singlet Oxygen during Photodynamic Treatment of Tumors
Research at APL has been directed at understanding energy transfer events taking place after laser excitation of photosensitive compounds in condensed media. In particular, optical means have been developed for the detection of electronically excited molecular oxygen (singlet oxygen) resulting from a favored energy transfer from the sensitizer triplet state. Oxygen excited in this manner is tho...
