The end-to-end CubeSat camera resolution, or rather spatial resolution, is best quantified by MTF. As a result, knowing the end-to-end MTF of a CubeSat Camera allows a systems engineer to make appropriate selection choices when optimizing the CubeSat Camera resolution for a specific application.
CubeSat Camera Resolution is all about resolving power, the amount of detail visible within an image. However, many prefer to define the spatial resolution in terms of Ground Sampling Distance (GSD) or Ground Resolved Distance (GRD), but how do you compare the GSDs and GRDs of different CubeSat Cameras qualitatively?
The Modulation Transfer Function (MTF) is a figure-of-merit that determines how much contrast is transferred from the original object to the detector and ultimately visible in an image. In short, it is all a function of how much the spatial frequencies are attenuated within the imaging path.
