title = "Liquid level sensing based on laser differential confocal detectors",
abstract = "Liquid level measurement plays an important part in industry and daily life. Applications include oil tanks, gasoline stations and public water supplies. Traditional electronic sensors cannot satisfy the demands in harsh environments. Recently, optical sensors have been particularly attractive in these applications. We propose a sensing method based on laser differential confocal detectors for discrete or continuous liquid level sensing. No target or supplementary device need to be immersed into the liquid. The sensitivity of the liquid level is about 0.01 mm with current systematic parameters. Measurement experiment of simulated liquid surface with a reflective mirror is carried out to verify the method.",
