For decades, I have been interested in the application of small-diameter aperture optics, or SDAO, to enhance visual function ...

Based on the application of the exact solution for the plane wave diffraction by a rectangular hole, the transmission property of a rectangular aperture less than the half-wavelength is investigated ...

A new publication from Opto-Electronic Advances, 10.29026/oea.2023.230039 discusses diffraction-limited visible imaging for large aperture telescopes.

The aperture you choose doesn't just affect depth of field and exposure, it affects image resolution too ...

RectangularDiffraction A MATLAB visualization of Fraunhofer diffraction of light by a rectangular aperture. Features: Calculates the intensity distribution, colors the figure by wavelength, and ...

K. Abedin, “Computer Simulation of Fresnel Diffraction from Rectangular Apertures and Obstacles Using the Fresnel Integrals Approach,” Optics and Laser Technol-ogy, Vol. 39, No. 2, 2007, pp. 237-246.

Here, we report a versatile soft x-ray diffraction microscope with 70- to 90-nm resolution by using two different tabletop coherent soft x-ray sources—a soft x-ray laser and a high-harmonic source. We ...
