Absolute measuring interferometric high-speed profilometer using wavelength modulation at ultrasonic frequencies

We present a laser interferometric approach for absolute distance measurements based on current-modulated laser diodes. The proposed system employs a point-wise measuring interferometer operating with two lasers of slightly different wavelengths in the telecommunications spectral range. By exploiting the modulated in...
