Computational approach to homodyne detection of interference phase
Original language description
Determination of the interference phase, i.e. the mutual phase shift between interfering waves is a principal issue in the interferometric measurement, especially on the nanometre scale. Our goal was to develop a novel interference phase detection technique that employs a computational approach and a frequency modulation of the laser source to achieve comparable performance with a homodyne detection with an optical phase shift generation. We have used a Michelson setup with polarizing optics that allowed to compare both the homodyne detection method and our novel method side by side while both methods shared the optical setup. Our method also comprises error compensation that deals e.g. with residual amplitude modulation and the scale non-linearities.The experiments revealed that the novel method achieves a periodic error less than 0.16 angular degrees and a standard deviation of less than 1.5 degrees, compared against the reference. The operational distance was 600mm. The method had
