Abstract
The potential of double-wavelength interferometry is well known, espec ially regarding the capability of performing absolute distance measure ments of rough targets with high resolutions. We describe the experime ntal results obtained with a demonstration model of a double-wavelengt h interferometer with superheterodyne detection. Our system, implement ed with two four-quadrant detectors to improve the detection probabili ty, has,demonstrated the ability to reach resolutions of 0.2 mm at 5-m distances on rough targets in 50-ms integration time.
