Advanced optical distance measurements using femtosecond laser pulses

摘要: Femtosecond lasers began to draw attention as a new light source for high-precision absolute distance measurements (ADMs) allowing advanced principles such synthetic wavelength generation, Fourier-transform-based dispersive analysis and multi-wavelength interferometry. In this talk, we present the state-of-the-art measurement performance demonstrated by exploiting unique temporal spectral characteristics of femtosecond laser pulses ADM applications.
