An international consortium led by the UK's National Physical Laboratory has set a new record for comparing ultra-stable lasers at long distances by metering a fibre network. A related research paper was published in the journal Nature Communications.

Laser sensors are sensors that use laser technology to measure. It consists of a laser, a laser detector and a measuring circuit. Laser sensor is a new type of measuring instrument. Its advantages are that it can realize non-contact long-distance measurement, fast speed, high precision, large range,......
