-\subsection{Delay Stages}

+MR-CMDS is subject to a number of possible artifacts, many of them stemming from the imperfect

+nature of the frequency-tunable light sources we currently have.  %

+It is self-evidently desirable to correct these artifacts, when possible.  %

+Indeed many of these artifacts, such as OPA power, phase mismatch and absorption effects have

+regularly been corrected for.  % TODO: link to examples in applications section

+These corrections are applied after measurement, typically including information from other sources

+(such as absorption spectra, in the case of absorption effect corrections).

 

-% TODO: discuss _all 3_ delay configurations.... implications for sign conventions etc

+A more interesting class of corrections are ``active'' corrections---that is, corrections that must

+be actively applied during acquisition and cannot be applied in post processing.  %

+These corrections are more insidious, and they are often neglected because the hardware and/or

+software does not allow for them.  %

 

-\section{Signal Acquisition}

+In this chapter I explore some of these active correction strategies that are useful in the context

+of MR-CMDS.  %

+Some of these strategies have already been implemented, others are partially implemented, and

+others are still just ideas.  %

+I hope to show that active correction is a particularly useful strategy in MR-CMDS.  %
