Method for Real-Time Controlled Selective Irradiation of a Predetermined Dose Onto a Target Zone of a Surface, and Corresponding System

A method for controlled selective irradiation of a target zone of a surface of a layer of material to allow local radiation of said target zone with a view to obtaining a target effect, consisting in polymerisation of the layer of material, said method being implemented by a system comprising an emitter device, at least one measurement and analysis device and a controller device, said method comprising:

• A) segmenting said surface into a plurality of zones;
• B) inputting into said controller device predetermined main energy thresholds respectively associated with each of said zones, and inputting said target effect to be obtained;
• C) choosing said target zone among the zones and combinations of the zones;
• D) irradiating said target zone by emission of energy radiation by said emitter device, said emission being controlled by said controller device with the goal of reaching said predetermined main energy thresholds;
• E) measurement and recording in real time, by said measurement and analysis device, of real energy generated by the energy radiation at said target zone;
• F) analysis and recording, by said measurement and analysis device, of a real effect obtained at said irradiated target zone;
• G) transmitting the measurement of said real energy and the analysis of said real effect to said controller device;
• H) controlling in real time of said emitter device by said controller device during the irradiation method, while taking into account said measurement of the real energy and said analysis of the real effect received,
• said measurement of real energy being compared to the predetermined main energy threshold associated with said target zone, and said analysis of the real effect being compared to said target effect, so that:
• H1) if said main energy threshold is not reached and said target effect is not obtained, the emission of energy radiation onto said target zone continues and a power and/or an intensity of said energy radiation is modulated to obtain said target effect;
• H2) if said main energy threshold is reached but said target effect is not obtained, the emission of energy radiation onto said target zone continues and the power and/or the intensity of said energy radiation is modulated to obtain said target effect;
• H3) if said main energy threshold is reached and the target effect is obtained, the emission of energy radiation onto said target zone is stopped;
• H4) if said main energy threshold is not reached but said target effect is obtained, the emission of energy radiation onto said target zone is stopped.
