Themis An4 analyzer principle

Anonymous (anonymous@undisclosed.example.com) — 2024-12-19T16:32:11+00:00

Themis An4 analyzer principle Themis An4 new polarimetric analyzer is a dual beam full-Stokes analyzer. The “modulator” part is made out of two quarter-wave plates and is quite similar in its principle to our former An2 (it actually uses the very same sets of crystaline retardance plates) or An3 (this version, while identical in the principle, was using twisted nematics LCDs retarders). The $\varphi$$$M_0(\varphi) = \left(\begin{array}{cccc} 1 & 0 & 0 & 0\\ 0 & 1 & 0 & 0\\ 0 & 0 & \cos\!\left(…

In real space $$I(\mathbf x)=O(\mathbf x)\star S(\mathbf x)$$ in Fourier space $$\hat I(\mathbf u)= \hat O(\mathbf u) . \hat S(\mathbf u)$$ Ensemble average for spectral densities: $$\langle | \hat I(\mathbf u)|^2 \rangle= | \hat O(\mathbf u)|^2 . \langle | \hat S(\mathbf u)|^2 \rangle $$ ... TBContinued ... Bispectrum $\hat T_p$ is the complex fourier tranform. the bispectrum (triple correlation) is: \begin{equation} \hat T_{p,q}^{(3)}=\hat T_p.\hat T_q. \hat T_{-p-q} \end{equation} prin…

Inline math tests (mathjax plugin) This is is a test: $a^2 + b^2 = c^2$ This is another test: $1+2+\dots+n=\frac{n(n+1)}{2}$ To display math on its own line, use double dollar signs: => $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$ gives: $$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$ or escaped square brackets: \[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]$\hat T_p$\begin{equation} \hat T_{p,q}^{(3)}=\hat T_p.\hat T_q. \hat T…
