Abstract:
An explosive circuit was designed. It was consist of laser source, laser detector, digital counter and detonator. It is excited by laser diode beam (695nm) from a transmitter. The circuit operates when the laser beam was transmitted and received by diode laser. The circuit starts digital counting from 1,2 ……to 15 and when it reached the final count at 15 it sends a signal to detonator which produced the explosive action. This circuit can be used in many different fields such as mining.
