Key Technological Features:

Optical System and Light Source:
Our Optical Wave Laser Range Finder utilizes a visible light semiconductor laser source (1) to emit an intense beam of light (20). The light undergoes precise optical adjustments through lenses, prisms, and mirrors, ensuring parallel alignment before being emitted through the objective lens (11). Simultaneously, reflected light (21) from the target is collected through the same optical path.

Photoelectric Conversion:
The device incorporates a sophisticated system involving a dichroic prism (12), a reflection prism (13), and a variable aperture (16) to direct the reflected light (21) into a fiber optic cable (14). The light then enters a light-emitting element (15) for efficient photoelectric conversion, generating electrical signals.

Pulse Drive Mechanism:
Employing a pulsed drive approach for the visible light semiconductor laser source (1) ensures the emission of a high-power light beam (20) for instantaneous measurements. This design enhances the device's capability to measure a wide range of targets within the visually safe output range.

Internal Calibration:
To guarantee measurement precision, a second semiconductor laser source (1-2) is employed for internal calibration. The two sources alternately handle distance measurement and internal calibration, providing a robust and reliable system.

Control System:
ERDI TECH LTD's Optical Wave Laser Range Finder features an intelligent control system powered by a microcomputer (25). This system processes signals, adjusts the variable aperture, and controls other optical components. External control signals are utilized for adjusting the device's elevation and azimuth, enhancing its multifunctionality.

Targeting and Calibration:
The device incorporates a precision targeting telescope for aligning with the target. Simultaneously, the emitted light (20) from the Optical Wave Laser Range Finder is directed toward the target to ensure accurate measurements.

Safety Considerations:
Safety is paramount. The visible light semiconductor laser source (1) is designed with safety measures to prevent prolonged exposure issues, ensuring the device's reliability.

Angular Measurements:
Angular measurements, including elevation and azimuth, are executed using the elevation axis (31) and the vertical axis (34). These measurements are precisely controlled through software programming to define measurement points.

Portability and Mobility:
Featuring handles on both sides for easy transportation, the device is also equipped with a power-driven mechanism for improved mobility, adding convenience to the measurement process.

In summary, ERDI TECH LTD's Optical Wave Laser Range Finder stands as a technological marvel, providing unprecedented precision in distance measurement. Its innovative design, incorporating advanced optics and intelligent control systems, makes it an indispensable tool for diverse applications requiring accurate and efficient distance measurements.
