Intensity and encircled energy for circular pupils obscured by strut supported central obscurations.
The intensity and encircled energy functions of an image formed by a diffraction-limited optical system with a strut supported centrally obscured circular pupil are derived and evaluated. Results presented give quantitative information on the reduction in energy in a focal plane area due to the presence of struts as a function of central and strut obscuration geometry.
