Analysis of Michelson interferometer operation in two measurement modes: touch-trigger and scanning, is carried out. A method is proposed for eliminating measurement errors introduced by longitudinal component of the speckle structure when the instrument is in trigger mode. The case of a relatively slow transverse component of random modulation of object signal is considered; the component is responsible for the emergence of the longitudinal component leadings to increased measurement errors. Requirements to the elements and settings of micro-scan are formulated.
