The invention relates to a method for calibrating the effective spatial resolution of an optical surface contour instrument by use of white noise PSD (power spectral density). White noise restricts the spatial resolution of the optical surface contour instrument, the white noise PSD is a constant ...

In summary, the conversation discusses the concept of white noise and its infinite power, despite having a finite variance. The definition of white noise is that it has a constant power spectral density (PSD) over all frequencies, leading to an infinite power when integrated. However, in ...
Assuming that we can model the noise as white noise, the power spectral density of the noise is given by: [5]E(f)=erms2(2fs) If we are dealing with a bandwidth of interest f0 (i.e., the maximum frequency of interest of the input signal is f0) we can get the expression for ...
A good introduction to the need for the concept of power spectral density is presented by Tustin [1]. I will paraphrase briefly. Suppose that Alice is trying to measure a random vibration. Assume that it is a stationary vibration (not changing in character with time) and that it is white...
1. During growth of the buffer layer, the power spectral density decreases for q > 2μm− 1 due to smoothing of the pitted surface, and increases for q < 2μm− 1, presumably due to kinetic roughening. After a thick layer has been deposited, the characteristic length for the ...
