J. Stone et al., CORRECTIONS FOR WAVELENGTH VARIATIONS IN PRECISION INTERFEROMETRIC DISPLACEMENT MEASUREMENTS, Journal of research of the National Institute of Standards and Technology, 101(5), 1996, pp. 671-674
Precision interferometric displacement measurements require deadpath c
orrections to account for variations in wavelength during the course o
f the measurement This paper discusses common errors in applying deadp
ath corrections and describes the correction necessary to fully accoun
t for variations in wavelength.
