Publish Time: 2024-09-11
The design principles of laser rangefinders involve multiple aspects, aiming to ensure the high accuracy, high reliability, long life and ability to adapt to various environments of the rangefinder.
1. High-precision design
Selection of measurement principle: High-precision laser rangefinders usually use phase laser ranging or triangulation. Phase ranging measures time indirectly by measuring the phase difference between the transmitted pulse and the received pulse, thereby calculating the distance, and its accuracy can reach millimeters or even micrometers. The triangulation method measures the distance by using the displacement of the light spot on the imaging surface through the triangular optical path formed by the light source, the measured object surface and the light receiving system.
Optical system design: High-quality optical lenses and reflectors are used to ensure the parallelism and focusing accuracy of the laser beam. At the same time, by optimizing the optical path and reducing scattering and loss in the optical path, the signal-to-noise ratio of the signal is improved, thereby improving the measurement accuracy.
Signal processing and algorithm: Advanced signal processing technologies such as digital filtering and signal enhancement are used to improve the clarity and accuracy of the received signal. At the same time, high-precision algorithms are used to process the data to ensure the accuracy of the measurement results.
2. High reliability design
Structural stability: Design a sturdy and durable mechanical structure to ensure that the rangefinder can maintain a stable working state in various environments. At the same time, a drive-free structure is adopted to reduce the wear and failure rate of mechanical parts.
Environmental adaptability: The laser rangefinder should have good environmental adaptability, including dustproof, waterproof, shockproof and other capabilities. By adopting the IP67 protection level that meets the environmental resistance standard and the standard air purge component, dust accumulation and pollution in front of the sensor head are prevented.
Temperature stability: Design circuits and systems with temperature compensation functions to ensure stable and reliable performance of the rangefinder under different temperature conditions. At the same time, the all-aluminum body and optical unit protection design are adopted to absorb shock and temperature changes through the external aluminum body to protect the internal optical unit from being affected.
3. Long life design
Wear-free design: The wear-free photoelectric measurement principle is adopted to reduce the wear and failure rate of mechanical parts. At the same time, the long-term stability and reliability of electronic components are ensured by optimizing circuit design and material selection.
Low power design: low power circuit design and efficient power management strategy are adopted to reduce the energy consumption and heat generation of the rangefinder, and extend the battery life and overall service life.
Easy maintenance: design component structures that are easy to maintain and replace, such as modular design, easy to disassemble and install components, etc., to reduce the difficulty and cost of maintenance.
4. User experience design
Ease of use: design intuitive and easy-to-use operation interface and operation process, so that users can quickly get started and accurately operate the rangefinder. At the same time, provide clear and concise measurement result display and prompt information to improve the user experience.
Portability: design a small and lightweight body structure for easy carrying and use by users. At the same time, provide a comfortable grip and a stable support method to ensure the stability and accuracy of the rangefinder during the measurement process.
Versatility: in addition to the basic distance measurement function, other auxiliary functions can also be designed, such as volume calculation, area calculation, angle measurement, etc., to meet the different needs of users.
The design principles of laser rangefinders cover many aspects such as high precision, high reliability, long life and user experience. By following these design principles, it can be ensured that the laser rangefinder can maintain excellent performance and stability in various environments.
