Displacement measurement with adjustable range by use of the photoelectromotive force effect and a frequency-modulated laser diode.
We demonstrate a scheme for displacement measurement by use of the photoelectromotive force effect and a frequency-modulated laser diode. The measurement range can be adjusted by a change in the depth of frequency modulation, thus making the measurement method both simple and versatile.
