Abstract

It includes at least one light source emitting time-varying optical energy to the detonator via an optical fibre. The detonator includes at least one photovoltaic cell to convert optical to electrical energy. There is a detector circuit to detect preset frequency or time lapses in the transmitted light. There is also a voltage multiplier, condenser for storage of the electrical energy, control switch and load cell. It is arranged that when the preset frequency or time lapse is detected, the stored energy is released to the load cell.
