In this paper, an optical heterodyne interferometric detection model with a frequency-ramped
laser diode (LD) has been analyzed. The effect of the nonlinearity of the LD source on the …

An optical heterodyne interferometer with a frequency-ramped laser diode has been
constructed. The effect of the beat frequency on the measured phase has been theoretically …

The nonlinearity of one-frequency optical interferometry with quadrature fringe detection is
the result of a number of factors including polarization mixing, unequal gain of detectors …

An area scan digital camera is used to record the full-field heterodyne interference signals,
and the processes to derive the associated phases from the data of the recorded frames …

The accuracy of a heterodyne interferometer is often limited by the periodic nonlinearity that
arises mainly from imperfect separation of the two optical frequencies. This paper describes …

This work addresses the problem of how birefringence and dichroism within a laser source
affect the linearity in heterodyne interferometry. A previous paper showed that of the two …

A simple method was proposed by using a tunable attenuator fitted in the reference or
measurement arm of a heterodyne laser interferometer to adjust the values of mixing laser …

We have proposed an approach to the interference phase extraction in the homodyne laser
interferometry. The method employs a series of computational steps to reconstruct the …

A striking abnormal harmonic is detected in the measurement signal spectrum of a
heterodyne laser interferometer, which deviates from the conventional frequency-domain …
