Area of Science:

• Optical Physics
• Microscopy Imaging

Background:

• Optical diffraction limits conventional microscope resolution.
• Modeling light intensity transmission and distribution is crucial for system development and pattern recognition.
• Existing models struggle to analytically link blur degree to camera parameters due to complex wave propagation.
