Area of Science:

• Optics and Photonics
• Computational Imaging

Background:

• Diffraction limits fundamentally constrain the resolution and accuracy of spot simulations in optical systems.
• Conventional simulation methods struggle with the large image planes required for complex systems like mosaic aperture telescopes due to high sampling demands.

Purpose of the Study:

• To develop a robust computational method for simulating optical system spots, specifically addressing challenges posed by diffraction limits and large image planes.
• To enable accurate analysis of spot translation and spreading in imaging systems, particularly those with wavefront discontinuities.

Main Methods:

• Application of the Fourier transform for calculating spot distributions in imaging systems.
• Development and implementation of an interpolation technique to align multiwavelength spots onto a uniform image plane grid.
• Adaptation of simulation parameters to accommodate larger image planes (approx. 10 mm) necessary for mosaic aperture telescopes.

Main Results:

• Successfully overcame the limitations of conventional methods in simulating optical spots for systems requiring extended image planes.
• Enabled precise alignment of multiwavelength spots, facilitating detailed analysis of spot behavior.
• Demonstrated effective analysis of spot translation and spreading under diffraction-limited conditions.

Conclusions:

• The proposed model provides an effective solution for simulating optical system spots, particularly for mosaic aperture telescopes with wavefront discontinuities.
• The interpolation technique enhances the accuracy and feasibility of analyzing diffraction-limited spot behavior on large image planes.
• This approach improves the fidelity of spot simulations, crucial for the design and evaluation of advanced optical systems.
