| Abstract: | The principle of distance measurement in pulsed laser radar is introduced and its key technology of time of flight(TOF)is discussed.TOF in laser pulsed distance measurement can be measured analogically,digitally,or using an interpolation method.The interpolation method,using the digital method combined with an interpolation method of three kinds,is a suitable way to employ a wide measurement range,high precision and accuracy,and a fast measurement speed for fast laser radar.And the three interpolation methods:delay line interpolation,the Nutt and dual Nutt principles,and the digital dual Vernier method,are described in detail in this paper. |
