ELECTRO-OPTICAL DEVICE AND METHOD FOR MONITORING SINGLET OXYGEN PRODUCED PHOTORADIATION USING PULSED EXCITATION AND TIME DOMAIN SIGNAL PROCESSING

摘要

in a process and apparatus for optical inspection of the singlet oxygen produced during the photoradiation, a composite optical emission in the frequency band.the 27 micron is detected and electronically processed to separate a first component due to the decay of the singlet oxygen from a second side component due to the fluorescence of dye photosensitization.a pulsed excitation source (16) is used to excite the dye photosensitization, and a signal processor (40) of the time, such as an integrator (28) to the value of the sample, is used to isolate and treat the singlet oxygen evolution in components the field of time.the magnitude and / or the other characteristics of the oxygen singlet emission component can be used to determine the properties of biological and other complex media. in therapy, the magnitude and / or the characteristics of the emission of singlet oxygen can be used by the physician to address a photodosimu00e8tre therapy.
