METHOD FOR INITIATING MULTI-CHANNEL LASER INITIATION SYSTEM Russian patent published in 2021 - IPC F42B3/113 

FIELD: physics.

SUBSTANCE: invention relates to the field of physics of explosion, methods and devices of non-contact detonation of industrial explosives and can be used in devices to ensure safety, control and initiation of explosive devices and pyrotechnic devices with an optical signal. The method of initiating a multichannel laser initiation system consists in monitoring the optical path of the system with a closed optical switch by forming and supplying first a control pulse and then an initiating pulse. After switching the optical switch to the open state, the optical path is monitored by generating and supplying a control pulse to the path of the initiating device. After initiation of the initiating device, its operation is checked with a control pulse. In this case, the control and initiating pulses are formed with the same amplitude and different duration for each laser emitter. One or simultaneously two control / initiation pulses are applied to one or two initiating devices, respectively, through a feed-through optical connector. The open / closed state of the optical switch is provided by moving the light filter of the optical switch to the open / closed state.

EFFECT: technical result consists in increasing the safety of the laser initiation system by ensuring control of the state of the optical path in each channel of the system.
