The infrared diode study in nanosecond pulse mode in information processing devices on a large distance

The light-emitting diode, as an electron device, capable of replacing a laser is investigated. As far as the radiation power of the light-emitting diode in a continuous mode is small (about 0.5 W), and in this case the distance of guaranteed connection does not exceed hundred of meters, the use of a light-emitting diode in nanosecond pulsed mode with large signal repetition were offered by us. In this case the radiation power is increased, multiplied on repetition, that is up to 5-50 W and it is comparable to laser power. The cost of the light-emitting diode thus is essentially less. Both the transmitter and receiver of the infrared pulses were developed. A general description of the system is presented.
