Employing a GHz-rate electro-optic comb, this method achieves accurate distance measurements with 4 µm precision, highlighting its effectiveness in distance gauging.
Using a single GHz-rate electro-optic comb in synthetic wavelength interferometry, we perform absolute distance measurement with a ±4-µm precision and 3.7-m non-ambiguity range. Three comb lines from the source are employed for this purpose.
