%X A focal length measurement method using inaccurate joint transform correlation technique is proposed.The joint power spectrum is recorded using lens of known focal length,and correlation spots are output by the lens to be measured.The correlation spots are recorded ,correlation spot interval is measured,and focal length can be calculated.The results show that the measurement precision is higher and the method can be potentially applied to focal length measurement automation.
