研究目的
Investigating the optimal design scheme of an integrated optical interferometric imaging system to improve imaging quality through simulation and optimization of structural parameters.
研究成果
The study concluded that increasing the number of baselines and interferometer arms improves imaging quality, with odd numbers of interferometer arms performing better. The system is most suitable for remote sensing imaging, requires waveguide fabrication accuracy on the order of magnitude of λ/10, and the proposed baseline optimization scheme significantly improves imaging quality without increasing system fabrication difficulty.
研究不足
The baseline distribution optimization scheme proposed is applicable to only a single wavelength, indicating a need for further research on multiwavelength baseline distribution optimization.
