- Abstract:
- A displacement measurement with an uncertainty of less than sub-nanometer is required in many industrial fields. A laser interferometer has become a powerful tool in nano-metrology, because the wavelength of the light source can be calibrated by meter definition. In this paper, we propose the use of sinusoidal phase (frequency) modulation on a laser diode (LD) to achieve both the frequency stabilization of the LD and a displacement measurement by a homodyne interferometer.
