| Abstract: | The principle of absolute distance measurement using a diode laser with current-induced frequency modulation is presented. The configuration of the interferometer is described. The experimental results show that the measurable range of the interferometer is 0.3 to 1.5meter with accuracy of 0.1 to 0.3mm. |
