Using a PMT/Monochromator, we have Surface Enchanced Raman Vials we are using to analyze samples.
One thing I am trying to figure out: The so called finger print region is 500-3000 wavenumbers after the wavelength of the laser you are using. In our case, we are currently using a 200mW 532nm...
I tried using Density Plot with this equation,letting theta approach zero, and tried varying t and I0 but still no luck.
For some reason, it doesn't seem very common to create fringe patterns digitally, or at least, I haven't really found any good info on it.
Probably help if I'd taken...
I am making an attempt at simulating interference patterns of a Fabry Perot interferometer.
I have fully derived the transmission function and the coefficient of finesse.
T=\frac{I0 T^{2}}{(1-R)^2} + \frac{1}{1+FSin^2(\frac{\delta}{2})}
Where F=\frac{4R}{(1-R)^2} and \delta =...
Derivative Using Dirac Delta Function
Homework Statement
Let \theta(x) be the step function:
\theta(x) be equivalent to
1, if x > 0
0, if x \leq 0
Show that \frac{d \theta }{dx} = \delta(x)
Homework Equations
In the previous portion I was able to prove
x \frac{d}{dx}...
Right now I am working with:
PMT: Hamamatsu R928/0115/0381

O-Scope: Tektronix TDS 5104 Oscilloscope
PMT Housing: PhotoCool Housing
PMT Housing Power Supply: PhotoCool Power Supply
Input: 200 mW 532 nm ND:YAG laser

Thinking through your method, I first tried converting x^2+y^2+z^2=4
to cylindrical and I got:
r(z)=\sqrt{4-z^2}
Then, I attempted a single integral with this equation:
I = \frac{1}{2}r^2\rho\int_{z_0}^r \sqrt{4-z^2}dz
where I assumed z_0=r-h for h=1 and r=2...
