DETONATOR Russian patent published in 2009 - IPC F42C1/00 F42C13/02 

FIELD: blasting works.

SUBSTANCE: invention relates to detonators and can be used in laser systems, working in complex environments (smoking, fog, rain, snow etc.). The detonator contains series-connected receiving-transmitting unit, processing unit, safety and arming system, electric detonator and payload. The input of the safety and arming system is connected to the output of a contact impact fuse. The detonator is provided with an optical pre-contact action system with working radius of 10-40 cm, consisting of series-connected pumping circuit and a light-emitting diode, for example, laser diode and series connected photodiode with an amplifier, normalising cascade, frequency dependent counter, threshold device and an actuating device. The light-emitting diode and the photodiode can establish optical connection with a target. The output of the actuating device is connected to the input of the safety and arming system.

EFFECT: increased efficiency.
