英文摘要：

A method based on Matlab FFT is presented for error correction and compensation of sensors. The measuring error curve analysis and its fitting algorithm of time grating displacement sensor can be got with the great command calculation of Matlab,which carry out to achieve high precision with low precision machined components measurement . As a result the precision of the sensor is promoted greatly.
