摘要
本文描述一台能改变光频移频率的新装置,它由旋转光栅、同步电机和调频电源组成。用该装置可方便地改变由于光栅旋转而产生的频移,从而使激光多普勒测量达到最佳的分辨率,以满足各种不同状态的测量。
A new device which can change the optical frequency shift is descrihed, It consists of a rotating grating, a synehro motor and a power supply whose frequency can be adjusted, Using this device, the frequency shift produced by the grating rotating can be changed conveniently so that the optimum revolution of laser doppler measurements can be obtained, and the measurements in various conditions will be satisfatory.
