Abstract
The properties offered by including a self-pulsating laser in a feedba ck loop for distance and cable length measurements are investigated. A simple method for the measurement of distance, displacement and cable length based on the unique properties of a self-pulsating laser is re ported. Measuring the main frequency peak of the regenerative oscillat ions under the condition of high gain, 30 mu m accuracy could be attai ned for a range of 3 cm.
