The structure of the laser level
The principle of using a microprocessor to control the scanning of the optical scanner is to project the laser onto the optical scanner, use the microprocessor and other hardware circuits to collect the horizon signal in real time, and then control the optical scanner to scan after processing. This design and manufacture of intelligent laser level. The laser level produces a laser line that is always kept parallel to the horizon in real time.
The optical scanner is a low-inertia scanner. An optimized and reasonable scanning control model is selected, and a microprocessor is used to control the optical scanner to realize the deflection of the beam, that is, the beam can be moved according to the control model, and the location can also be randomly selected. To move the light beam, this working method has very strong functions, and has the characteristics of high speed and high precision, which is intelligent optical scanning. In terms of national economy and military technology, for example, laser microcomputer, laser scanning ophthalmoscope, laser marking machine, large-screen art display, infrared front-view system and other technologies, it has broad application prospects.
The laser level is a comprehensive instrument integrating optics, machinery, electronics, and computer. The instrument is divided into two parts, one is the host part, and the other is the projector part; the host part collects the attitude signal or manual signal of the horizon. The signal is calculated and processed, and the optical scanning system is controlled to scan in real time. The projector part uses the laser system (including semiconductor laser, laser power supply and optical system) and optical scanning system to generate a laser scanning line under the control of the host computer, and projects it in any direction and position in the two-dimensional space. This scanning line is always parallel to the horizon.
