Rayleigh criterion depth of focus

WebIn acoustical lenses both resolution and depth of focus are determined by diffraction and the smaller the lens aperture the worse the resolution and the greater the depth of focus. Diffraction-limited resolution has a Soret Zone Plate, but a long depth of focus has an axicon. Nevertheless, these are two different devices each of which requires its own … WebThe Rayleigh criterion is the most well known and it reflects the fact that combustion instability occurs when the heat release rate and the pressure fluctuation ...
