Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

The problem of the diffraction of electromagnetic waves by a circular aperture in an infinitely conducting planar screen is studied. Attention is focused chiefly on the low frequency end of the ...

Place the laser on top of the lab jacks, making sure the laser is pointed away from people. Place the slide mount on the optical rail and insert the sample slide to the slide mount. Plug in the laser ...

Sieve analysis continues to be the traditional and most widely used technique for particle size determination. A sieve stack contains a number of sieves with increasing aperture size stacked upon each ...

Fundamental diffraction physics says that a larger aperture improves both resolution and penetration. However, aperture size has historically been limited by system complexity and unknown benefit in ...
