Description

TECHNICAL FIELD

The disclosure relates to the field of laser measurement technologies, and particularly to a dual-optical fusion laser rangefinder.

BACKGROUND

Existing laser rangefinders include pulse laser rangefinders and phase laser rangefinders. The pulse laser rangefinders can measure distances from 3 meter (m) to 5000 m, but their measurement accuracy is not high, with an error of +1 m at 100 m, and the error tends to increase as the measurement distance becomes longer. The phase laser rangefinders can measure distances from 0.2 m to 200 m and offer high measurement accuracy, with an error of ±2 millimeter (mm) at 10 m. However, as with the pulse laser rangefinders, the error of the phase laser rangefinders also tends to increase with the measurement distance becoming longer, and the phase laser rangefinders cannot measure as far as the pulse laser rangefinders. Currently, there is no rangefinder on the market that can measure long distances while also ensuring millimeter-level accuracy.
