Holo focus on researching and producing laser level and laser distance meter, which are mainly applied in the field of construction and decoration.
Laser distance meter use laser for measurement, featuring high precision and the ability to cross obstacles, while ultrasonic measuring instruments rely on sound waves. Ultrasonic waves propagate in a conical shape
Due to the extremely narrow single pulses of a laser distance measurer —with the transmitting pulse width only several nanoseconds and the receiving pulse width at most about 20 nanoseconds—the sampling rate
The core of a laser distance meter is to calculate the round-trip time of the laser (one-way time × speed of light = distance). In recent years, many industries have
