Fourier transform spectrometerThe principle and fundamental structure of a millimeterwave electric-field cross-correlation Fourier transform spectrometer are presented. In the spctrometer, two pseudorandom binary sequences (PRBS) with controllable phase variation are used to modulate individually two wide ...

The conventional urban gravity model based on Newton's Law of Universal Gravitation is made into a new expression based on a cross-correlation function. Endowed with a time-lag parameter and time functions, the developed model can integrate temporal dimension into spatial process of cities. A ...

If you calculate the cross-correlation at multiple lags, you can Fourier transform the lags into a cross-power spectrum. The phase-slope of that spectrum is the relative delay of the correlated signal in the two inputs. Cheers, Dave Translate 0 Kudos Copy link Reply Altera_Forum ...
(discrete FT) to dramatically reduce computation time and memory without sacrificing accuracy. With this procedure all the image points are used to compute the upsampled cross-correlation in a very small neighborhood around its peak. This algorithm is referred to as the single-step DFT al...
from the optical to the electrical domain and vice versa [3]. Additionally, the proposed system is fully relying on the physical properties of optical materials to achieve the cross correlation instead of mathematical computations, consequently, allowing for dealing with data in its more natural ...
Using real-time and single-shot amplified dispersive Fourier transform spectroscopy simultaneously with high-fidelity cross-correlation frequency resolved optical gating at femtojoule sensitivity and femtosecond resolution, we examine the soliton stability limits, the soliton dynamics including free-carrier ...
