ABSTRACT:
Distance measurement by conventional optical interferometry requires physical movement of an optical element. The present system obtains interference with a continuous range of radiation wavelengths, providing a direct measurement of a constant optical path difference, in terms of the fringe count and the end wavelengths of the range employed. Variations in the optical path difference occurring during the measurement are compensated by simultaneous interferometry with a fixed wavelength.
