发明名称 SYNCHRONIZED PERIOD MEASURING SYSTEM
摘要 An improvement in optical magnetometers whereby the accuracy of the output signal is increased. The depumping frequency is determined by measuring the time interval for a predetermined number of cycles to occur. Error due to sweeping the depumping frequency is prevented by making the sweep frequency a sub-multiple of the depumping frequency.
