DEVICE FOR SKIN TREATMENT BASED ON MULTI-PHOTON SKIN TREATMENT Russian patent published in 2017 - IPC A61B18/20 

FIELD: medicine.

SUBSTANCE: device uses polarized light to initiate a multi-photon ionization process at a target location in the skin tissue and comprises a light source configured to generate linearly polarized probe light and linearly polarized treatment light, a polarization modulator configured to control the direction of probe light polarization and the direction of treatment light polarization, a polarization-sensitive sensor to perceive the level of probe light depolarization and a controller configured to receive a measurement signal (Sm) from the sensor and provide a control signal (Sc) to the polarization modulator and the light source so as to scan the direction of probe light polarization over a predetermined range of polarization directions during the reception of the measurement signal (Sm), and to select the optimal polarization direction (P1), for which the level of probe light depolarization (12) is minimal. The device is supplemented with a software product, made with an ability to control the device.

EFFECT: application of the group of inventions helps to reduce the intensity of light emission.
