| In order to solve the problem that current electro-optic (EO) electric field sensor has no continuous power supply capability,
a pulsed electric field sensor powered by laser photocell is designed and developed. The sensor consists of a laser photocell power supply
circuit, an EO modulation circuit and a monopole antenna. The laser photocell power supply circuit which incorporated with a diode
laser, a lithium battery, a photovoltaic power converter, a lithium battery charging, protection and discharge circuit are designed and
fabricated. The experimental results show that the output voltage accuracy and ripple coefficient of the developed laser photovoltaic power
supply circuit are 1. 04 % and 0. 3% respectively. Besides, the output voltage fluctuation is ±0. 035 V after continuous work for 48
hours. The EO modulation circuit of the sensor incorporated with a monopole antenna and a FET type operational amplifier is designed
and fabricated. The measurement results show that the dynamic range of the developed sensor is from 0. 256 kV/ m to 13. 79 kV/ m. |
