【Abstract】 This thesis presented a new type of space elcetric field measurement system,which uses the Pockels effect of the crystal to modulate a light beam.The modulated light beam,which reflects the magnitade of the electric field,is coverted to electric signal by photeeffect before being detected by the signl detecting circuit.Then single-chip computer is used to do the data collecting and processing,thus to realize the measurement of the electric field.更多还原
