SUMMARY
The discussion centers on the impact of different aperture shapes—circle, triangle, and square—on encircled energy after diffraction, specifically for apertures measuring 300um in diameter. Participants agree that while the area of the aperture is crucial for energy transmission, the shape influences the diffraction pattern and consequently the center of gravity (COG) of the resulting spots on a camera sensor. The mathematics of Fresnel diffraction is suggested as a complex but relevant framework for understanding these variations, particularly in applications like planet-finder telescopes that utilize diverse aperture shapes to enhance resolution.
