Acceleration measurements upon micro- and nanodisplacements of an object using the autodyne signal of a semiconductor laser with allowance for the external optical feedback

The effect of the external optical feedback in a semiconductor laser autodyne on the acceleration measurements for the nonuniformly accelerated micro- and nanodisplacements of an object is analyzed. It is demonstrated that the correlation coefficients of the results of the acceleration measurements and the approximating linear dependence are 0.99 and 0.82 with allowance for and disregard of the feedback level, respectively.
