High resolution is achieved by dithering the knife-edge in the scan direction. The method is equivalent to the slit method but with a variable slit width also on a sub-μm scale. A signal-to-noise ratio of 10 6 : 1 has been demonstrated. bough beeches blvd https://daniutou.com

WebKnife Edge Model The path loss due to diffraction in the knife edge model is controlled by the Fresnel Diffraction Parameter which measures how deep the receiver is within the shadowed region. A negative value for the parameter shows that the obstruction is below the line of sight and if the value is below -1 there is hardly any loss.
