Rayleigh depth of focus

Webfocused, the greater the depth of field and, the smaller the diameter of beam handling optics needed. In Depth: The Beam Parameter Product (BPP). In some cases, people prefer the Beam Parameter Product (BPP) in order to specify beam quality (alternatively to the Beam Quality Factor M²). The Beam Parameter Product of a laser beam is defined as WebMar 18, 2004 · In this article, we have systematically investigated the dependencies of k 1 on illumination conditions such as coherence setting and opening angle in off-axis illumination scheme. As result, conventional Rayleigh’s equations are not sufficient to address the effect of the numerical aperature and coherence on the depth of focus. Therefore, a metric …

Web4. RESOLUTION EXCEEDING THE RAYLEIGH LIMIT AND THE EXTENDED DEPTH OF FOCUS. With the scheme described in Section 3, the resolution of the reconstructed images is limited by the numerical aperture of the objective in exactly the same way as it is limited in a conventional wide-field image. WebMar 15, 2024 · The main disadvantage of the electromagnetic acoustic transducer (EMAT) is low energy-conversion efficiency and low signal-to-noise ratio (SNR). This problem can be improved by pulse compression technology in the time domain. In this paper, a new coil structure with unequal spacing was proposed for a Rayleigh wave EMAT (RW-EMAT) to …
