| Abstract: | It is theoretically analysed that the measure precision of long wavelength laser is difficult to improve by laser wavelength measure device. An improved algorithm is proposed by using DFT for precisely measuring the frequency of a finite length periodic sequence. The simulation result indicates that the algorithm is practical. Also the measurement range is enlarged. |
