"WebThe theoretical maximum optical resolution of optics is determined by diffraction effects of light which mainly depend on the wavelength of the light and the slit (aperture). According to the Rayleigh criterion (remaining contrast of approx. 15 per cent), two image points can still be distinguished when the distance of the points dx = 2 * 1.22 * f-stop * wavelength.

The imaging system's resolution can be limited either by aberration or by diffraction causing blurring of the image. These two phenomena have different origins and are unrelated. Aberrations can be explained by geometrical optics and can in principle be solved by increasing the optical quality of the system. On the other hand, diffraction comes from the wave nature of light and is determin… WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR).
