研究目的
To meet the distortion requirements of an ultra-low-distortion optical system by analyzing the relationship between primary aberrations and tolerances, and proposing a method to reduce distortion sensitivities through optimization.
研究成果
The proposed method effectively reduces distortion sensitivities in ultra-low-distortion optical systems by optimizing primary aberrations, allowing for relaxed tolerances without increasing costs. Monte Carlo analysis confirms significant improvements in distortion control under the same tolerance conditions.
研究不足
The method may not fully address high-order aberrations, and optimization could increase other aberrations like spherical aberration if not carefully managed. Application is specific to ultra-low-distortion systems and may not generalize to all optical designs.
1：Experimental Design and Method Selection:
The study involves theoretical analysis of aberration-tolerance relationships, optimization of primary aberrations using optical design software, and Monte Carlo simulations for tolerance analysis.
2：Sample Selection and Data Sources:
An ultra-low-distortion telecentric optical system is designed with specific parameters (e.g., wavelength

6 Optical design software (Zemax) is used for simulations; no physical equipment is specified.
4：Experimental Procedures and Operational Workflow:
Steps include designing the optical system, analyzing tolerance sensitivities, optimizing primary aberrations, and performing Monte Carlo analyses to evaluate distortion.
5：Data Analysis Methods:
Statistical analysis of Monte Carlo results to assess distortion distribution and sensitivity reductions.
