Abstract
A simple heterodyne interferometer associates with phase to amplitude conversion and amplitude sensitive technique is proposed. The excess noise and the quantum noise introduced by the autocorrelations between sensing beam and local oscillator beam are reduced at suitable phase bias. Meanwhile, the differential phase arises from target displacement is detected by optical differential and optical additive operations. The amplitude and phase quadrature are also achieved simultaneously in proposed interferometer.
