Contrary to popular belief (Goodman even leads his readers this direction) a lens does not perform a Fourier Transform. A lens is only helpful in displaying and manipulating the Fourier transform.
What creates the Fourier transform is the coherent light interacting with the fine structure of...
Hey all,
I am trying to find a function which will give me a family of curves similar to the one shown below. What I am hoping is that a single parameter will control whether the curve starts out slow (like the blue one) or whether the curve starts out fast (like the green one) or whether it...
Thanks for helping me think through my question. Is this similar to how we determine the at rest mass of an electron? As far as I know an electron is never actually at rest.
How does the concept of frame of reference apply to quantum mechanics? Classically something can be a frame of reference as long as it is not accelerating. I often picture in my head an atom with the nucleus fixed and the electron cloud surrounding it. Would it be possible to describe an atom...
I have some findings to report:
I have written a program which can generate up to order 6 successfully, but when my code attempts to do order 7 it chokes (24 hours + with no solution returned!).
After googling around some more I found a poster presentation which describes the problem using...
I am working on the applications but I found the matrix by analyzing the matching card game Spot it! It is a card game which has 8 symbols per card with one and only one matching symbol between any two cards. If you follow the link above you can play a demo.
Hey all, I have been playing around with a special type of matrix and am wondering if anyone knows of some literature about it. I have been calling it a pseudo-orthogonal matrix but would like to learn if it has a real name or if we can come up with a better name. The characteristics of the...
I could probably help but your question does not have enough information for me to figure out what the issue is. Is the issue with the FFT or with the plotting? Do you need help creating the frequency vector with which to plot the fft of your signal? What does not look correct?
If your spectrum is rising above the sinc^2 envelope then you must have some other source of energy corrupting your system. I would guess that you have some irregularity in your pulse width (called Duty Cycle Distortion (DCD)).
From the text of your post it sounds like you are sending a...
