I. In-depth Analysis of Core Influencing Factors in High-Precision Environments
In high-precision scenarios, environmental factors—such as fluctuations in the refractive index of air, deformation of equipment or samples, damage to optical components, and circuit interference—can significantly impact measurement accuracy, machining precision, and equipment stability. Among these, the core influencing factors can be categorized into the following types:
(1) Fluctuation Factors of Atmospheric Optical Properties
The fluctuations in the refractive index of air (n) are one of the primary sources of error in high-precision optical instruments, such as laser interferometers and optical measuring devices. According to the differential equation describing changes in air's refractive index, variations in temperature (t), pressure (p), relative humidity (rh), and carbon dioxide concentration (x) influence the system through partial derivatives, ultimately leading to
\(\Delta n\)
The cumulative effect of (changes in refractive index) subsequently triggers fluctuations in the laser wavelength, leading to measurement errors.
Temperature: Fluctuations in temperature directly alter the thermal motion of air molecules, affecting not only the refractive index of air but also causing instruments and measured samples to deform due to thermal expansion and contraction.
Pressure gradient: Pressure fluctuations can alter the distribution of air density, while factors such as wind speed and noise further exacerbate the instability of the pressure gradient, thereby intensifying fluctuations in the refractive index of air even more.
Relative humidity: Changes in humidity affect the amount of water vapor in the air. Since water vapor has significantly different optical properties compared to dry air, this leads to substantial fluctuations in the refractive index.
Carbon dioxide concentration: The optical scattering properties of CO₂ molecules differ from those of the surrounding air, and fluctuations in its concentration can directly disrupt the overall optical uniformity of the atmosphere.
(II) Other Environmental Disturbance Factors
In addition to the optical properties of air, the following environmental factors also pose critical threats to high-precision scenarios:
Cleanliness: Dust and particles in the air can adhere to the surfaces of optical components such as lenses, crystals, and gratings, creating diffraction effects that alter the light field distribution. In some cases, high-energy light may even burn out optical elements due to localized hotspots.
Micro-vibrations—caused by equipment operation, human activity, or even external traffic—can induce jitter in instruments, components, and samples, leading to misalignment of optical paths and directly compromising the stability of measurements and manufacturing processes.
Electromagnetic interference: The circuit systems of high-precision instruments are highly sensitive to electromagnetic signals, and external electromagnetic disturbances can lead to abnormal device control and distorted measurement data.
Grounding resistance: Excessive grounding resistance can easily lead to static electricity buildup, which not only interferes with measurement and manufacturing processes but may also cause irreversible damage to sensitive electronic components.
