To find the find the focal point of ours lens and the proper placement of our sample and detector, we use the equation  \[ \frac{1}{f_{o}}=\frac{1}{d_{o}}+\frac{1}{d_{1}} \]  where $f_{o}$ is the focal length of the particular lens, and $d_{o}$ and $d_{1}$ are the distances of the sample and the detector relative to the lens [2]. \textbold{To be continued with fourier stuff as well as Equally sloped tomography}
