The light emitted by the solar \TR\ and corona varies significantly as a function
of position, wavelength, and time.

$\lambda$ is wavelength, and $t$ is time.
The ideal solar imaging spectrograph would capture $I(x, y, \lambda, t)$ with high resolution in $x$, $y$, $\lambda$,
and $t$ \textit{and} over a wide \FOV\, wavelength range, and time period.
Of course, the temporal dimension is privileged, so we often reduce the problem to capturing a 3D spatial/spectral

privileged: This makes no sense to me.

Approaching this ideal is the fast tunable filtergraph (\ie\ fast tunable Fabry--P\'erot etalons, \eg\ the GREGOR
Fabry--P{\'e}rot Interferometer, \citep{Puschmann12}), but the materials do not exist to extend this technology to
\EUV\ wavelengths shortward of $\sim$\SI{150}{\nano\meter}~\citep{2000WuelserFP}.

and $t$ \textit{and} over a wide \FOV\, wavelength range, and time period.
Of course, the temporal dimension is privileged, so we often reduce the problem to capturing a 3D spatial/spectral
cube at a particular time $t_0$: $I(x, y, \lambda, t_0)$.
Since we use 2D detectors, this means that we must find a way to flatten the 3D cube into two dimensions

...we use 2D detectors to capture an exposure at some time $t$...
Instead of "the 3D cube...without losing information", how about "the remaining three dimensions $x$, $y$, $\lambda$. This will probably entail some loss of information, which we must manage to meet our scientific goals."
